Passing pointers of strings to native lib function

Postby jstadolnik on Tue Dec 12, 2000 4:03 am

Passing a pointer of a string to a native library function does not work. The MemHandle of the string ends up pointing to garbage.

Here is a native library function which shows the problem:

void junk(PocketCLibGlobalsPtr gP) {
Value address, *ptr;
gP->pop(address);
ptr = gP->deref(address.iVal);
Char *text = (Char*) MemHandleLock(ptr->sVal);
WinDrawChars(text,20,10,80);
MemHandleUnlock(ptr->sVal);
}
