pub fn access_syscall(path: impl AsRef<Path>, mode_mask: c_int) -> Result<bool>
Safe wrapper to the libc::access
syscall.

Used by:
This function requires a bitmask made of:
libc::R_OK
(Read)libc::W_OK
(Write)libc::X_OK
(Execute)
To check for each given rwx
permission, or:
libc::F_OK
(File exists)
Otherwise, the function fails with Err(kind: InvalidInput)
Examples:
use permissions::access_syscall; use libc::{R_OK, W_OK, X_OK, F_OK}; fn main() -> std::io::Result<()> { assert!(access_syscall("src/lib.rs", R_OK | W_OK)?); assert!(access_syscall("/", R_OK | X_OK)?); assert!(access_syscall(".", F_OK)?); assert!(!access_syscall("src/lib.rs", X_OK)?); assert!(!access_syscall("/root", W_OK)?); Ok(()) }
