A newsgroup discussing unix would probably be a better place to ask this
question. iirc, there is no such function call in any of the unixes I
know, but there might be in other flavours.

Yes, with unix these functions are probably the way to go. Think
'recursion'. The find utility probably relies on those functions as
well. Note that these functions are defined by Posix, and not part of
standard ANSI C.

tx.

tx ?

Some unixes have a function "ftw" or functions with names beginning
"fts" that do this sort of thing. According to one manual page, "the
fts utility is expected to be included in a future IEEE Std
1003.1-1988 (POSIX.1) revision", so you might look for a Posix-related
group or web site.

You can do most any command line with something like
system("find /usr/local -name '*mysql*' >find-output");
FILE *f = fopen("find-output","r");
...
fclose(f);

If you're willing to restrict yourself to Posix, you can do something like
FILE *f = popen("find /usr/local -name '*mysql*' >find-output","r");
...
pclose(f);
