actually it goes something like this
CharPtr foo;
foo=MemPtrNew(50);
result=MyCall(foo);
DoSomething(foo);
MemPtrFree(foo);
/-----------------------------/
int MyCall(CharPtr food) {
switch(MemPtrResize(food, 100)) {
case memErrChunkLocked
FrmCustomAlert(TestAlert, "fails here!!", " ", " ");
break;
}
}

Is your pointer really a pointer to a chunk, or is it just a pointer to
global or stack memory? That is,
char foo[SOMESIZE];
char *ptr = foo;
MemPtrResize(ptr, SOMEOTHERSIZE);
will not work. You can only resize a chunk that you've gotten with
MemHandleNew, MemPtrNew, DmNewHandle, or DmNewRecord.
