 * Title:	dclarea.c
 * Author:	Thomas E. Dickey
 * Created:	13 Apr 1985
 * Last update:
 *		19 Feb 1995, prototyped
 *		15 Jun 1985, typed 'calloc'
 *		13 Apr 1985
 *
 * Function:	Allocate a string-area for a DCLOPT-table entry so we needn't
 *		have a lot of large static buffers lying around.
 *
 * Arguments:	name	- name of entry to find in table 'opt[]'.
 *		size	- number of bytes to allocate
 *		opt[]	- DCLOPT array of permissible options
 *		size_opt - sizeof(opt[]).
 *
 * Returns:	Pointer to the allocated area.  The DCLOPT entry also points
 *		to this area.
