FEXECVE(3) Linux Programmer's Manual FEXECVE(3)
fexecve - execute program specified via file descriptor
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 appro-
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
ENOSYS The /proc file system could not be accessed.
fexecve() is implemented since glibc 2.3.2.
This function is Linux-specific. It is under consideration for inclu-
sion in a future version of POSIX.1.
