One way of getting the name of the current (or any) executing program 
is to use the proc filesystem on SVR4. The following C program 
will do the needful.

/*
 * Gets the name of the current command/process  - raj
 */
#include <stdio.h>
#include <ctype.h>
#include <string.h>
#include <fcntl.h>
#include <sys/stat.h>
#include <sys/procfs.h>


main()
{
        int     procfd;                 /* fd for /proc/xxxxx */
        char    pname[20];
        int     pid = getpid();
        struct  prpsinfo info;          /* process ps info */


        printf ("my pid = %d\n",pid);   /* use the pid of process */
        sprintf(pname, "/proc/0%d",pid);
        if ((procfd = open(pname, O_RDONLY)) == -1) {
                printf("could not open /proc/%s\n",pname);
                exit(1);
        }                                    
			  	        /* read the info from /proc */
        if (ioctl(procfd, PIOCPSINFO, (char*)&info) == -1) {
                printf("ioctl on open /proc/%s failed\n",pname);
                close (procfd);
                exit(2);
        }
        close(procfd);
        printf("my command name = %s\n",info.pr_fname);
}
