NAME

6       fexecve - execute program specified via file descriptor
7

SYNOPSIS

9       #include <sys/time.h>
10
11       int fexecve(int fd, char *const argv[], char *const envp[]);
12

DESCRIPTION

14       fexecve() performs the same task as execve(2), with the difference that
15       the file to be executed is specified via a file descriptor, fd,  rather
16       than via a pathname.
17

RETURN VALUE

19       A  successful  call to fexecve() never returns.  On error, the function
20       returns, with a result value of -1 is returned, and errno is set appro‐
21       priately.
22

ERRORS

24       Errors are as for execve(2), with the following additions:
25
26       EINVAL fd  is  not a valid file descriptor, or argv is NULL, or envp is
27              NULL.
28
29       ENOSYS The /proc file system could not be accessed.
