fexecve — execute program specified via file descriptor
#define _GNU_SOURCE #include <sys/time.h>
int
fexecve( |
int | fd, |
| char *const | argv[], | |
| char *const | envp[]); |
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.
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 are as for execve(2), with the following additions:
fd is not a
valid file descriptor, or argv is NULL, or
envp is
NULL.
The /proc file system
could not be accessed.
This function is Linux-specific. It is under consideration for inclusion in a future version of POSIX.1.
