Function pelite::util::wstrn

pub fn wstrn(buf: &[u16]) -> &[u16]

Reads an optionally nul-terminated wide char string from buffer.

Returns the slice split before the nul word and the whole slice if no nul word is found.

Analog to the wcsn* family of C string functions.

Examples

use pelite::util::wstrn;

let buf: [u16; 8] = [83, 84, 82, 73, 78, 71, 0, 0];
assert_eq!(wstrn(&buf), &[83, 84, 82, 73, 78, 71]);

let buf: [u16; 4] = [70, 79, 85, 82];
assert_eq!(wstrn(&buf), &[70, 79, 85, 82]);
