+.IP \fIptr\fP 1i

+.SH DESCRIPTION
+The
+.ZN 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,
+.ZN XtMalloc
+calls
+.ZN XtErrorMsg .
+.LP
+The
+.ZN 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,
+.ZN XtCalloc
+calls
+.ZN XtErrorMsg .
+.LP
+The
+.ZN 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,
+.ZN XtRealloc
+calls
+.ZN XtErrorMsg .
+If ptr is NULL,
+.ZN XtRealloc
+allocates the new storage without copying the old contents;
+that is, it simply calls
+.ZN XtMalloc .
+.LP
+The
+.ZN XtFree
+function returns storage and allows it to be reused.
+If ptr is NULL,
+.ZN XtFree
+returns immediately.
+.LP
+.ZN XtNew
+returns a pointer to the allocated storage.
+If there is insufficient memory to allocate the new block,
+.ZN XtNew
+calls
+.ZN XtErrorMsg .
+.ZN XtNew
+is a convenience macro that calls
+.ZN XtMalloc
+with the following arguments specified:
+.LP
+.Ds
+.TA .5i
+.ta .5i
+((type *) XtMalloc((unsigned) sizeof(type))
+.De
+.LP
+.ZN XtNewString
+returns a pointer to the allocated storage.
+If there is insufficient memory to allocate the new block,
+.ZN XtNewString
+calls
+.ZN XtErrorMsg .
+.ZN XtNewString
+is a convenience macro that calls
+.ZN XtMalloc
+with the following arguments specified:
+.LP
+.Ds
+.TA .5i
+.ta .5i
+(strcpy(XtMalloc((unsigned) strlen(str) + 1), str))
+.De
+.LP
+The
+.ZN 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,
+.ZN XtAsprintf
+calls
+.ZN XtErrorMsg .
