XtFree()																  XtFree()

Name
  XtFree - free allocated memory.

Synopsis
  void XtFree(ptr);
	 char *ptr;

Inputs
  ptr	    Specifies the address of the allocated memory to be freed.

Description
  XtFree()  frees  a  block of memory previously allocated by XtMalloc(), XtRealloc(), XtCalloc(), XtNew() or XtNewString() so that it can be
  reused by the system.

  If ptr is NULL, XtFree() returns immediately.

Usage
  The ptr argument is of type char *.  In many cases, you will have to cast the data you are freeing to this type in order to  avoid  warning
  messages from your compiler.

  A  number  of  Xt  functions return strings or other values that must be freed with XtFree() when the caller will no longer need them.  You
  should be sure to check the documentation of any function that returns a value to find out who "owns" the memory and	who  is  expected  to
  free it.

  Calling  the	Toolkit's XtMalloc() and XtFree() is more portable and provides better error checking than calling system-specific malloc and
  free.  You should not use XtFree() on memory that was allocated with malloc() or other non-Xt memory allocation routines.
