If cmd is - * a full or relative path, it is checked but PATH locations are not scanned. - * search_path will put the resulting path in res_path. It is assumed - * that res_path points to a string that is at least PATH_MAX - * (or MAXPATHLEN on the suns) in size. Access_mode is just as is - * says, the mode to be used on access to determine if cmd can be found. - * If fullpath is set, res_path will contain the full path to cmd. - * If it is not set, res_path may or may not contain the full path to cmd. - * If fullpath is not set, the path in PATH prepended to cmd is used, - * which could be a relative path. If fullpath is set, the current - * directory is prepended to path/cmd before access is called. - * If cmd is found, search_path will return 0. If cmd cannot be - * found, 1 is returned. If an error has occurred, -1 is returned - * and an error mesg is placed in res_path. - * If the length of path/cmd is larger then PATH_MAX, then that path - * location is skipped. - * - *#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#**/ - -#include <stdio.h> -#include <unistd.h> -#include <string.h> -#include <stdlib.h> -#include <sys/errno.h> -#include <sys/param.h> -#include <sys/stat.h> - -extern int errno; - -struct stat stbuf; - -#ifndef AS_CMD -#define AS_CMD 0 -#endif - -/* - * Make sure PATH_MAX is defined.
