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
file system 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)
file system, so
/proc
needs to be mounted and available at the time of the call.
