# NAME

`wcscasecmp`, `wcsncasecmp` —
compare wide-character strings, ignoring case

# LIBRARY

Standard C Library (libc, -lc)

# SYNOPSIS

`#include <wchar.h>`

int
`wcscasecmp`(const wchar_t *s1, const wchar_t *s2);

int
`wcsncasecmp`(const wchar_t *s1, const wchar_t *s2, size_t len);

# DESCRIPTION

The `wcscasecmp`() and `wcsncasecmp`() functions compare the nul-terminated strings s1 and s2 and return an integer greater than, equal to, or less than 0, according to whether s1 is lexicographically greater than, equal to, or less than s2 after translation of each corresponding character to lower-case. The strings themselves are not modified.

The `wcsncasecmp`() function compares at most len characters.

# SEE ALSO

wcscmp(3)

# STANDARDS

The `wcscasecmp`() and `wcsncasecmp`() functions conform to IEEE Std 1003.1-2008 (“POSIX.1”).

# HISTORY

The `wcscasecmp`() and `wcsncasecmp`() functions first appeared in NetBSD 4.0.

# NOTES

If len is 0, `wcsncasecmp`() always returns 0.
