[Scottish] type of files

[Huard, Elise - D C&W Consultant]

Hello,

may be slightly off-topic, but not completely : how do you access the type
of a file in a C program (under Linux/Unix) ?
using the path, i want to be able to determine whether it is a shell, an
executable ...
What i found looking in my C book and browsing through man pages : the
f_flags of filehdr should give some indication, apparently.  Unfortunately i
don't know how to get to this filehdr, and i studied every stdio function i
could think of.
There's always the rather inelegant call to 'system()' using 'file' command,
but there must be a nicer way.

(this might be a stupid question but i've not programmed in C that much)

Thanks,

Elise
