Function exec_through_gate 

unsafe fn exec_through_gate(
    path: *const c_char,
    argv: *const *const c_char,
    envp: *const *const c_char,
) -> i64

execve through the allow gate. Allocation free.

Arguments

• path - Program to exec.
• argv - Its argument vector.
• envp - Its environment.

Returns

The negative errno of a failed exec; a successful one does not return.

Safety

map_gates must have succeeded, and the pointers be valid for execve.
