XtMalloc(3Xt)															     XtMalloc(3Xt)

NAME

       XtMalloc, XtCalloc, XtRealloc, XtFree, XtNew, XtNewString - memory management functions

SYNOPSIS

       char *XtMalloc(size);
	       Cardinal size;

       char *XtCalloc(num, size);
	       Cardinal num;
	       Cardinal size;

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

       void XtFree(ptr);
	       char *ptr;

       type *XtNew(type);
	       type;

       String XtNewString(string);
	       String string;

ARGUMENTS

       Specifies  the  number  of bytes or array elements.  Specifies a pointer to the old storage or to the block of storage that is to be freed.
       Specifies the size of an array element (in bytes) or the number of bytes desired.  Specifies a previously  declared  string.   Specifies  a
       previously declared data type.

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
       allocate 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 insufficient 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 the allocated storage.	If there is insufficient memory to allocate the new block, XtNewString calls XtEr-
       rorMsg.	XtNewString is a convenience macro that calls XtMalloc with the following arguments specified:

       (strcpy(XtMalloc((unsigned) strlen(str) + 1), str))
