 *  RES.C - Resource handling for FreeCOM
 *
 *	Contains all functions specific for FreeCOM
 *
 *	int enumResources(altFnam, res_majorid_t, int (*fct)(), void * arg)
 *		Searches for all resources of the specified major ID in the
 *		primary resource file, which is usually the execuatble itself.
 *		On "open error: (rc == -1) the alternate filename "altFnam" is
 *		tried, too.
 *		The callback function is called like this:
 *			int fct(res_majorid_t, res_minorid_t, length, int, arg)
 *		The "length" parameter specifies the length of the data
 *		block (unsigned long), the int fd is the resource file opened
 *		in "r+b" modus <<be careful!!>>, "arg" is the pointer passed to
 *		enumREsources().
 *		The callback function may reposition the file, though, the file
 *		itself must not be closed.
 *
 *		If the callback function returns 0 (zero), the loop continues,
 *		otherwise enumResource() is terminated and this value is returned.
 *
 *
 *	Return:
 *		0: Nothing found or callback function always returned "0" itself
 *		else: return value of callback function
 *		-1: file open error
 *

	This file bases on OPENF.C of FreeCOM v0.81 beta 1.
