This is similar to @code{execve}, but instead identifying the progam
executable by its pathname, the file descriptor @var{fd} is used. The
descriptor must have been opened with the @code{O_RDONLY} flag or (on
Linux) the @code{O_PATH} flag.
On Linux, @code{fexecve} can fail with an error of @code{ENOSYS} if
@file{/proc} has not been mounted and the kernel lacks support for the
underlying @code{execveat} system call.
