I get a FILE * pointer by calling popen. Now I want to change it into a
file descriptor. Is there a function call for it? Like fdopen create a
FILE* out of a file descriptor.

Thanks,

You probably want	int fileno(FILE *);
but it doesn't really "change" the file pointer to a descriptor -
it provides the descriptor associated with the already open file pointer.

Google for 'fileno'.
