XtMalloc(3)			 XT FUNCTIONS			   XtMalloc(3)

NAME
       XtMalloc, XtCalloc, XtRealloc, XtFree, XtNew, XtNewString - memory man-
       agement functions

SYNTAX
       #include	<X11/Intrinsic.h>

       char *XtMalloc(Cardinal size);

       char *XtCalloc(Cardinal num, Cardinal size);

       char *XtRealloc(char *ptr, Cardinal num);

       void XtFree(char	*ptr);

       type *XtNew(type);

       String XtNewString(String string);

       Cardinal	XtAsprintf(char	**new_string, const char *format, ...);

ARGUMENTS
       num	 Specifies the number of bytes or array	elements.

       ptr	 Specifies a pointer to	the old	storage	or to the block	of
		 storage that is to be freed.

       size	 Specifies the size of an array	element	(in bytes) or the num-
		 ber of	bytes desired.

       string	 Specifies a previously	declared string.

       type	 Specifies a previously	declared data type.

       new_string
		 Specifies a pointer to	write a	newly allocated	string to.

       format	 Specifies a formatting	string as defined by sprintf(3c)

DESCRIPTION
       The XtMalloc functions returns a	pointer	to a block of storage of at
       least the specified size	bytes.	If there is insufficient memory	to al-
       locate the new block, XtMalloc calls XtErrorMsg.

       The XtCalloc function allocates space for the specified number of array
       elements	of the specified size and initializes the space	to zero.  If
       there is	insufficient memory to allocate	the new	block, XtCalloc	calls
       XtErrorMsg.

       The XtRealloc function changes the size of a block of storage (possibly
       moving it).  Then, it copies the	old contents (or as much as will fit)
       into the	new block and frees the	old block.  If there is	insufficient
       memory to allocate the new block, XtRealloc calls XtErrorMsg.  If ptr
       is NULL,	XtRealloc allocates the	new storage without copying the	old
       contents; that is, it simply calls XtMalloc.

       The XtFree function returns storage and allows it to be reused.	If ptr
       is NULL,	XtFree returns immediately.

       XtNew returns a pointer to the allocated	storage.  If there is insuffi-
       cient memory to allocate	the new	block, XtNew calls XtErrorMsg.	XtNew
       is a convenience	macro that calls XtMalloc with the following arguments
       specified:

	    ((type *) XtMalloc((unsigned) sizeof(type))

       XtNewString returns a pointer to	a new string which is a	duplicate of
       string.	If there is insufficient memory	to allocate the	new block, or
       the argument is NULL XtNewString	returns	NULL. The memory can be	freed
       with XtFree.

       The XtAsprintf function allocates space for a string large enough to
       hold the	string specified by the	sprintf(3c) format pattern when	used
       with the	remaining arguments, and fills it with the formatted results.
       The address of the allocated string is placed into the pointer passed
       as ret.	The length of the string (not including	the terminating	null
       byte) is	returned.  If there is insufficient memory to allocate the new
       block, XtAsprintf calls XtErrorMsg.
