fexecve (3)
FEXECVE(3) Linux Programmer's Manual FEXECVE(3)
NAME
fexecve - execute program specified via file descriptor
SYNOPSIS
#include <sys/time.h>
#define _GNU_SOURCE
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.
