fexecve(3) - Linux man page
Name
fexecve - execute program specified via file descriptor
Synopsis
#include <sys/time.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.
