FEXECVE(3)		   Linux Programmer's Manual		    FEXECVE(3)

NAME
       fexecve - execute program specified via file descriptor

SYNOPSIS
       #include <unistd.h>

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

   Feature Test Macro Requirements for glibc (see feature_test_macros(7)):

       fexecve():
	   Since glibc 2.10:
	       _XOPEN_SOURCE >= 700 || _POSIX_C_SOURCE >= 200809L
	   Before glibc 2.10:
	       _GNU_SOURCE

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.  The file descriptor fd must be opened read-only,
       and the caller must have permission to execute the file that it	refers
       to.

RETURN VALUE
       A  successful  call to fexecve() never returns.	On error, the function
       returns, with a result value of -1, 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 filesystem could not be accessed.

VERSIONS
       fexecve() is implemented since glibc 2.3.2.

CONFORMING TO
       POSIX.1-2008.   This  function is not specified in POSIX.1-2001, and is
       not widely available on other systems.

NOTES
       On Linux, fexecve() is implemented using	 the  proc(5)  filesystem,  so
       /proc needs to be mounted and available at the time of the call.

SEE ALSO
