IUGetItlTable

Return a handle to the 'itl2' or 'itl4' resource

void IUGetItlTable( script, tableCode, itlHandle, offset, length );

ScriptCode script ; code indicating script

short tablecode ; indicates specific resource table

Handle *itlHandle ; handle to 'itl2' or 'itl4' resource

long *offset ; pointer to table offset from start of resource

long *length ; pointer to length of resource

Given a script code and a table code, IUGetItlTable returns a handle to

the 'itl2' or 'itl4' resource that contains the table, the offset of the specified

table from the beginning of the resource, and the length of the resource. At

present, the supported table codes are as follows:

Table code symbol Retrieves

iuWordSelectTable Word selection break table ('itl2')

iuWordWrapTable Word wrap break table ('itl2')

iuNumberPartsTable Default number parts table ('itl4')

iuUnTokenTable Untoken table ('itl4')

iuWhiteSpaceList White space list table ('itl4')

routines that accept script or language codes. For these routines, the data

types ScriptCode and LangCode are defined as follows:

typedef  short ScriptCode;
typedef  short LangCode;

Valid values for a parameter of type ScriptCode are integers in the range

0-64 that explicitly indicate a particular script, or one of the following

negative values:

Constant Meaning

iuSystemScript System script

iuCurrentScript Current script (from FontScript)

IUGetItlTable only checks the default 'itl2' or 'itl4' resource for the

script-that is, the 'itl2' or 'itl4' resource whose ID is specified in the

script's local variables. The itlHandle parameter is set to 0 for any of the

following error conditions: the script or the table code is in valid; the script

is not installed or not enabled; or the required resource can not be found or

is not in the current format.

the white space list table, see The 'itl4' Resource. For details on the

default number parts table and the untoken table, consult Macintosh
