What library do I link to my OS9 mac program to provide support for
execl() (which is defined in the unistd.h include file). Note that I
am already linking to the GUSI compatibility lib.

Hello dj_ingenuity,

I am sorry to say, that the best I can determine, GUSI does not
include a library that implements execl. I downloaded a copy of GUSI
2.2.0 from ...
  ftp://sunsite.cnlab-switch.ch/software/platform/macos/src/mw_c
onto my MacOS X machine, expanded the archive, and did...
  grep -irac execl . | grep -v :0
  ./include/unistd.h:1
which indicates the string "execl" only occurs in that one header file
and in no other file. From the change log for 2.2.2, at
  http://sourceforge.net/project/showfiles.php?group_id=7941&release_id=78422
the changes do not appear to have affected this capability.

Depending on your compiler, I could probably track down an equivalent
function. If that would be acceptable, please clarify your question to
allow alternatives and indicate which compiler you are using.

we are using codewarrior on OS9.

Hello dj_ingenuity,

I am still not sure, so this is not a billable answer. The best I can
determine
from on line documentation is from the Codewarrior MSL C Reference. As
I expected, execl support is basically a wrapper for exec. You can
call other programs with command line arguments, but the specific
semantics of execl may not be supported.

It does not say exactly which library exec is in, but there is a
listing of libraries required for Sioux and I would expect one of
those libraries to include exec.

I hope this helps. If not, the question is still open to someone else
to answer.
