NAME
wcsncasecmp - compare two fixed-size wide-character strings, ignoring case SYNOPSIS
#include
int wcsncasecmp(const wchart *s1, const wchart *s2, sizet n); Feature Test Macro Requirements for glibc (see featuretestmacros(7)): wcsncasecmp(): Since glibc 2.10: XOPENSOURCE >= 700 || POSIXCSOURCE >= 200809L Before glibc 2.10: GNUSOURCE DESCRIPTION The wcsncasecmp() function is the wide-character equivalent of the
strncasecmp(3) function. It compares the wide-character string pointed
to by s1 and the wide-character string pointed to by s2, but at most n wide characters from each string, ignoring case differences (towup‐ per(3), towlower(3)). RETURN VALUE
The wcsncasecmp() function returns zero if the wide-character strings at s1 and s2, truncated to at most length n, are equal except for case distinctions. It returns a positive integer if truncated s1 is greater than truncated s2, ignoring case. It returns a negative integer if truncated s1 is smaller than truncated s2, ignoring case. VERSIONS The wcsncasecmp() function is provided in glibc since version 2.1.

POSIX.1-2008. This function is not specified in POSIX.1-2001, and is not widely available on other systems. NOTES The behavior of wcsncasecmp() depends on the LCCTYPE category of the current locale. SEE ALSO strncasecmp(3), wcsncmp(3) COLOPHON
