ZstrCompareIgnoreCase

Documentation

API Reference

Description

Compare two strings lexicographically, ignoring ASCII case. Non-ASCII bytes are compared as-is (no Unicode case folding).

Returns 0 if equal under ASCII-case folding, <0 if lowered s1 < lowered s2, >0 otherwise.

Aborts via LOG_FATAL when either string pointer is NULL.
