Switched to `type *name' style Andrew Koenig's ``C Traps and Pitfalls'' (Ch.2.1) convinced me that it is best to go with the way C had been designed. The ``declaration reflects use'' concept conflicts with a ``type* name'' notation. Hence I switched.

FILE *peopen(const char *command, const char *type, char *const envp[], int *ret_pid);

FILE *peidopen(const char *command, const char *type, char *const envp[], int *ret_pid, uid_t uid, gid_t gid);
