2638.0. "Ques. Concerning Xt memory allocation/deallocation" by FREZEN::PROJECTS () Mon Apr 23 1990 13:20

There has been some talk in the vaxc conference pertaining to the use of
malloc/realloc/alloc/free/cfree

As for XtCalloc/XtMalloc/XtFree ...
Are there any conflicts in decwindows with the uses of one with the other.
Is there a documented rule set for using these.
Can using one with the other or vise versa cause conflict.

Thank you

	The main rule is don't mix the DECwindows functions (XtMalloc, XtCalloc, XtFree) with the non-DECwindows functions (malloc, calloc, free). If you obtain memory with malloc(), free it with free(), not XtFree(). Vice versa, if you get your memory with XtMalloc(), be sure to free it with XtFree(). --PSW
