A recent reply pointed at an entry in the Knowledge Base that
described the in-memory format of the tSTL (string list) resource.
There is a NUL-terminated "prefix string" (which I assume is to be
used to describe the subject of the list) followed by a short int set
to the number of entries in the list, followed by the list entries
themselves, all NUL-terminated.
The following code can be used to walk through each string
in turn:
file://- test code
VoidHand hFontChoices;
Char *pFontChoices;
int nFontChoices;
int i;
hFontChoices = DmGet1Resource('tSTL', FontChoicesStringList);
pFontChoices = MemHandleLock(hFontChoices);
pFontChoices += StrLen(pFontChoices)+1; // scan off the "prefix string"
nFontChoices = *(short *) pFontChoices; // get the # of entries
pFontChoices += sizeof(short); // increment over the
short
for (i=0; i<nFontChoices; i++) { // for each entry
...
// do something w/ string entry #i
pFontChoices += StrLen(pFontChoices)+1; // point to next entry
}
MemHandleFree(hFontChoices);
file://- end test code
