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

NAME
       fexecve - execute program specified via file descriptor

SYNOPSIS
       #define _GNU_SOURCE
       #include <unistd.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 appro‐
       priately.

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	inclu‐
       sion in a future version of POSIX.1.

SEE ALSO
       execve(2)
