Okay, here's a quick CL version... If tmpnam is successful, the return value (&PTR, below) will point to the same memory as &STORAGE. Storage will be a C-style (zero-terminated) string... to turn it back into a fixed-length CL char field, I use the C strlen() function to get the length, and then just substring it out...


PGM PARM(&FILENAME)

DCL VAR(&FILENAME) TYPE(*CHAR) LEN(40)
DCL VAR(&STORAGE) TYPE(*CHAR) LEN(40)
DCL VAR(&PTR) TYPE(*PTR)
DCL VAR(&NULLPTR) TYPE(*PTR)
DCL VAR(&LEN) TYPE(*INT) LEN(4)

CALLPRC PRC('_C_IFS_tmpnam') +
PARM((&STORAGE *BYREF)) +
RTNVAL(&PTR)
IF (&PTR *NE &NULLPTR) DO
CALLPRC PRC('strlen') PARM((&PTR *BYVAL)) +
RTNVAL(&LEN)
IF (&LEN *GT 0) DO
CHGVAR VAR(&FILENAME) VALUE(%SST(&STORAGE 1 &LEN))
ENDDO
ENDDO

ENDPGM

That would be cool Scott. I do it in RPG, but I need it in a CL, and didn't
want to have to switch languages. Thanks!

This API returns a pointer, not a character field...

Would recommend doing this in RPG where it's simpler, but if you need to
do it in CL, I could whip up an example...

So my code looks like this:

PGM PARM(&FILENAME)

DCLPRCOPT DFTACTGRP(*NO) ACTGRP(*CALLER) BNDDIR(QC2LE)
DCL VAR(&FILENAME) TYPE(*CHAR) LEN(40)

CALLPRC PRC('_C_IFS_tmpnam') PARM((*OMIT *BYVAL)) +
RTNVAL(&FILENAME)

ENDPGM

Seems pretty straightforward, but it's returning NULL (all hex zeroes
anyway).

Anyone see a problem?

Thanks!
