IdAlert()
Synopsis
LONG IdAlert(
ULONG id,
struct TagItem * taglist );
LONG IdAlertTags(
ULONG id,
TAG tag, ... );
Function
Get a human readable description of the alert ('Guru') code.
Inputs
Code -- (ULONG) alert code, as defined in exec/alerts.h
TagList -- (struct TagItem *) tags that describe further
options.
Tags
IDTAG_DeadStr -- (STRPTR) Alert type string (deadend or
recoverable). You may skip this tag if you do not
want to get the string.
IDTAG_SubsysStr -- (STRPTR) String of the subsystem that caused
the alert (CPU, exec.library, ...). You may skip this tag
if you do not want to get the string.
IDTAG_GeneralStr-- (STRPTR) General alert cause. You may skip
this tag if you do not want to get the string.
IDTAG_SpecStr -- (STRPTR) Specified alert cause. You may skip
this tag if you do not want to get the string.
IDTAG_StrLength -- (UWORD) Maximum length of the string buffer,
including termination. Defaults to 50.
IDTAG_Localize -- [V8] (BOOL) FALSE to get English strings
only, TRUE for localized strings. This is useful for
applications with English as only language. Defaults to TRUE.
Result
Error -- (LONG) error code, or 0 if everything went fine.
IdEstimateFormatSize()
Synopsis
ULONG IdEstimateFormatSize(
STRPTR string,
struct TagItem * tags );
ULONG IdEstimateFormatSizeTags(
STRPTR string,
TAG tag, ... );
Function
Estimates the size of the buffer that will contain the output of the format string when used on IdFormatString().
Inputs
String -- (STRPTR) Format string Tags -- (struct TagItem *) Tags, currently NULL or TAG_DONE.
Tags
None yet.
Result
Length -- (ULONG) Length of the buffer size that will
be able to hold the entire result.
Notes
The returned size will be large enough to contain the result of a IdFormatString(). It is not necessarily the size of the resulting buffer (the result length of IdFormatString()).

IdExpansion()
Synopsis
LONG IdExpansion(
struct TagItem * taglist );
LONG IdExpansionTags(
TAG tag, ... );
Function
Gets the name and class of the expansion and it's manufacturer.
Inputs
TagList -- (struct TagItem *) tags that describe further options.
Tags
IDTAG_ConfigDev -- (struct ConfigDev *) ConfigDev structure
containing all information. You should use this tag if ever
possible, since there are more possibilities to recognize and
distinguish between a board.
IDTAG_ManufID -- (UWORD) Manufacturer ID if ConfigDev is not
provided. You must also provide IDTAG_ProdID!
IDTAG_ProdID -- (UBYTE) Product ID if ConfigDev is not
provided. You must also provide IDTAG_ManufID!
IDTAG_ManufStr -- (STRPTR) Pointer to a buffer space for the
manufacturer name. You may skip this tag if you do not want
to get this string.
IDTAG_ProdStr -- (STRPTR) Pointer to a buffer space for the
product name. You may skip this tag if you do not want
to get this string.
IDTAG_ClassStr -- (STRPTR) Pointer to a buffer space for the
product class. You may skip this tag if you do not want to get
this string.
IDTAG_StrLength -- (UWORD) Buffer length, including
termination. Defaults to 50.
IDTAG_Expansion -- [V6] (struct ConfigDev **) Use this tag to
easily traverse through the expansion board list. Init the
pointed variable with NULL. After each call, you will find
the current ConfigDev pointer in this variable. If you are
done, this function returns IDERR_DONE and the variable is set
to NULL. See example.
IDTAG_Secondary -- [V7] (BOOL) If set to TRUE, identify will
warn about secondary expansions. E.g. some graphic boards
create more than one entry in the expansion list. Then, one
entry is the primary entry, and any additional are secondary.
This tag does only make sense when checking all mounted
expansions. Defaults to FALSE. (See Bugs)
IDTAG_ClassID -- [V8] (ULONG *) The ULONG field will be filled
with a numerical class ID of the expansion (see include file:
IDCID_...). IMPORTANT: You MUST be prepared to get a number
that does not match to any IDCID value. In this case, assume
IDCID_MISC.
IDTAG_Localize -- [V8] (BOOL) FALSE to get English strings
only, TRUE for localized strings. This is useful for applications
with English as only language. Defaults to TRUE.
Result
Error -- (LONG) error code, or 0 if everything went fine.
IDERR_NOLENGTH -- IDTAG_StrLength has been set to 0!
IDERR_BADID -- IDTAG_ManufID and IDTAG_ProdID were
out of range or one of them was missing.
IDERR_DONE -- Checked all expansions using the
IDTAG_Expansion tag. This is not really an error.
IDERR_SECONDARY -- This expansion is secondary to a primary
expansion entry.
Example
To check all expansion boards, you may use this code:
void PrintExpansions(void)
{
struct ConfigDev *expans = NULL;
char manuf[IDENTIFYBUFLEN];
char prod[IDENTIFYBUFLEN];
char pclass[IDENTIFYBUFLEN];
while(!IdExpansionTags(
IDTAG_ManufStr ,manuf,
IDTAG_ProdStr ,prod,
IDTAG_ClassStr ,pclass,
IDTAG_Expansion,&expans,
TAG_DONE))
{
Printf("Current ConfigDev = 0x%08lx\n",expans);
Printf(" Manufacturer = %s\n",manuf);
Printf(" Product = %s\n",prod);
Printf(" Expansion class = %s\n\n",class);
}
}
Notes
This function isn't implemented yet. If the manufacturer or the product is not known, the string will be filled with its number. This call is guaranteed to preserve all registers except D0.
Bugs
You must also provide IDTAG_ProdStr if you want to use IDTAG_Secondary.
IdFormatString()
Synopsis
ULONG IdFormatString(
STRPTR string,
STRPTR buffer,
ULONG len,
struct TagItem * tags );
ULONG IdFormatStringTags(
STRPTR string,
STRPTR buffer,
ULONG len,
TAG tag, ... );
Function
The buffer will be filled with the format string until
the format string terminates or the buffer size is reached.
The format string may contain format tags, which are
surrounded by dollar signs. Doing so, the printf formattings
are kept for a following printf.
Format tags are case sensitive!
If you want to write a dollar sign, then double it: '$$'.
These format tags are known:

Inputs
String -- (STRPTR) Format string
Buffer -- (STRPTR) Buffer to be filled with the result
until the format string terminates or the buffer
size is reached.
Length -- (ULONG) Length of the buffer, including the
null termination.
Tags -- (struct TagItem *) For future compatibility.
You must provide NULL or a pointer to TAG_DONE.
Result
Length -- (ULONG) Length of the buffer that really
has been used.
Example

IdFunction()
Synopsis
LONG IdFunction(
STRPTR libname,
LONG offset,
struct TagItem * taglist );
LONG IdFunctionTags(
STRPTR libname,
LONG offset,
TAG tag, ... );
Function
Decodes the offset of the provided library name into function name. This function requires the .fd files in a drawer with 'FD:' assigned to it. All files must have the standard file name format, e.g. 'exec_lib.fd'. The appropriate .fd file will be scanned. The result will be cached until the identify.library is removed from system.
Inputs
LibName -- (STRPTR) name of the function's library, device
or resource. All letters behind the point (and
the point itself) are optional. The name is
case sensitive.
Examples: 'exec.library', 'dos', 'cia.resource'.
Offset -- (LONG) offset of the function. It must be a
multiple of 6. You do not need to provide the
minus sign.
Examples: -456, 60
TagList -- (struct TagItem *) tags that describe further
options.
Result
Error -- (LONG) error code, or 0 if everything went fine.
- TAGS
- IDTAG_FuncNameStr -- (STRPTR) Buffer where the function name
- will be copied into.
- IDTAG_StrLength -- (UWORD) Maximum length of the string buffer,
- including termination. Defaults to 50.
Bugs
Every line in the .fd file must have a maximum of 254 characters. Otherwise the internal offset table may be corrupted (but the system won't be harmed). Anyhow, this should be no problem.
IdHardware()
Synopsis
CONST_STRPTR IdHardware(
ULONG type,
struct TagItem * taglist );
CONST_STRPTR IdHardwareTags(
ULONG type,
TAG tag, ... );
Function
Gets information about the current system environment. The result is returned as read only string. This function is fully DraCo compatible! Once a information has been evaluated, it will be cached internally, so changes will be ignored. Use IdHardwareUpdate() to clear the cache contents.

Notes
Some results are nonsense on AROS. If you queried a version, you'll find the version in the *lower* UWORD (because it is more important) and the revision in the *upper* UWORD. All memory sizes are always in bytes. Boolean results are ==0 for FALSE, !=0 for TRUE. If you have to look up the result in the include file, you might also get a numerical result that is beyond the maximum value you'll find there. Be prepared for it! In this case, just print "not known" or anything similar, or use the IdHardware() result.

IdHardwareUpdate()
Synopsis
void IdHardwareUpdate();
Function
Once a hardware information has been evaluated, the result will be stored in an internal cache. All subsequent queries return the cache contents, irregarding of any changes. This function invalidates the cache and forces identify to re-check ALL hardware features. Useful if e.g. the amount of memory has changed after VMM has been started. Use this function wisely. DO NOT call it just to make sure to get the latest information, let the user decide to do so. Also, DO NOT call it when you will only query hardware information that will for sure not change while run-time, e.g. CPU. IDHW_VBR, IDHW_LASTALERT and IDHW_TCPIP are NOT cached, so there is absolutely no need to call IdHardwareUpdate() just to check them out.
Bugs
Calling this function in identify V8.0 will lead to a system crash. This has been fixed in V8.1.
