NAMEwcsncasecmp - compare two fixed-size wide-character strings, ignoring case
#include <wchar.h>int wcsncasecmp(const wchar_t *s1, const wchar_t *s2, size_t n);
Feature Test Macro Requirements for glibc (see feature_test_macros(7)):
- Since glibc 2.10:
- _POSIX_C_SOURCE >= 200809L
- Before glibc 2.10:
DESCRIPTIONThe wcsncasecmp() function is the wide-character equivalent of the strncasecmp(3) function. It compares the wide-character string pointed to by s1and the wide-character string pointed to by s2, but at most nwide characters from each string, ignoring case differences (towupper(3), towlower(3)).
RETURN VALUEThe wcsncasecmp() function returns zero if the wide-character strings at s1and s2, truncated to at most length n, are equal except for case distinctions. It returns a positive integer if truncated s1is greater than truncated s2, ignoring case. It returns a negative integer if truncated s1is smaller than truncated s2, ignoring case.
VERSIONSThe wcsncasecmp() function is provided in glibc since version 2.1.
