fexecve

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 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.
