Module `helpers`

Small helper functions used inside sys.

If any of these have uses outside of sys, please move them to a different module.

Modules

c_opaque
small_c_string
wstr This module contains constructs to work with 16-bit characters (UCS-2 or UTF-16)

Structs

COpaque A wrapper for an opaque C object.
WStrUnits A safe iterator over a LPWSTR (aka a pointer to a series of UTF-16 code units terminated by a NULL).

Functions

ignore_notfound
mul_div_u64 Computes (value*numerator)/denom without overflow, as long as both numerator*denom and the overall result fit into u64 (which is the case for our time conversions).
