This is more of a programming question, so please let me know if there's a better place to ask. Our project (Swish-e) runs external programs via popen() and system(). Some of the external programs are placed in our $libexecdir which is not normally in the $PATH. We initially used setenv() to add our $libexecdir to $PATH, but setenv() doesn't seem to be portable (not sure it exists on Windows, for example). So the current plan is to read $PATH, prepend (or append) our $libexecdir to the path, and then walk the path looking for the program. The problem is how to do it in a portable way. I'll probably use the GNU Which(1) source as a base, but I'm wondering if anyone here has or knows of code to do this in a portable way. I expect VMS and Windows will give us the most trouble. Any pointers? Thanks, -- Bill Moseley moseley@xxxxxxxx
