NAME

       fexecve - execute program specified via file descriptor

SYNOPSIS

       #define _GNU_SOURCE
       #include <sys/time.h>

       int fexecve(int fd, char *const argv[], char *const envp[]);

DESCRIPTION

       fexecve() performs the same task as execve(2), with the difference that
       the file to be executed is specified via a file descriptor, fd,  rather
       than via a pathname.

RETURN VALUE

       A  successful  call to fexecve() never returns.  On error, the function
       returns, with a result value of  -1  is  returned,  and  errno  is  set
       appropriately.

ERRORS

       Errors are as for execve(2), with the following additions:

       EINVAL fd  is  not a valid file descriptor, or argv is NULL, or envp is
              NULL.

       ENOSYS The /proc file system could not be accessed.

VERSIONS

       fexecve() is implemented since glibc 2.3.2.

CONFORMING TO

       This  function  is  Linux-specific.   It  is  under  consideration  for
       inclusion in a future version of POSIX.1.
