wcsncasecmp ? 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); |
The wcsncasecmp function is the wide-character equivalent of the strncasecmp 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 (towupper, towlower). |
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. |
This function is a GNU extension. |
strncasecmp(3), wcsncmp(3) |
The behaviour of wcsncasecmp depends on the LC_CTYPE category of the current locale. |
