Subject:	Re: C and logical names via sys$trnlnm???
This worked for me (extracted & modified slightly from
SYS$EXAMPLES:OSIT$RANDOM.C) on ALPHA.

#include <descrip.h>
#include <ssdef.h>
#include <stdio.h>
#include "sys$library:lnmdef"

int     SYS$TRNLNM ();

#define RET_BUF_SIZE  64

void main ()
{
        unsigned int status;
        static char lnamebuf [RET_BUF_SIZE];
        unsigned int attr;
        $DESCRIPTOR (lname, lnamebuf);
        $DESCRIPTOR (lognam, "SOME_LOGICAL");
        $DESCRIPTOR (tabnam, "LNM$PROCESS_TABLE");
        struct
                {
                unsigned short int bufsiz;
                unsigned short int itmcod;
                char *bufadr;
                unsigned int retlen;
                unsigned int endoflist;
                } itmlst;

        attr = LNM$M_CASE_BLIND;
        itmlst.bufsiz = RET_BUF_SIZE;
        itmlst.itmcod = LNM$_STRING;
        itmlst.bufadr = lname.dsc$a_pointer;
        itmlst.retlen = (unsigned int)&(lname.dsc$w_length);
        status = SYS$TRNLNM (&attr, &tabnam, &lognam, 0, &itmlst);
        printf("Translation: %s", lnamebuf);
}
