= strnicoll =
''Microsoft-specific C function - not part of ANSI C''

== Syntax ==
:{{int strnicoll(const char* s1, const char* s2, int n)}}

== Arguments ==
:'''s1'''
::Pointer to the string to compare.
:'''s2'''
::Pointer to the string to which the first string is compared to.
:'''n'''
::The maximum number of characters to compare.

== Return ==
:An integer value indicating the result of the comparison.

== Description ==
:Compares two strings, up to the n maximum number of characters, based on the rules of the current system locale, in a case-insensitive manner.
:If zero is returned, both strings are identical. If a negative value is returned, string '''s1''' is found to be less then '''s2'''. If a value positive and greater then zero is returned, string '''s1''' is greater than '''s2'''.
:Characters are compared by their locale collation order - that is, the dictionary order for the locale. So while in extended ASCII accented characters come after all a-z characters, in a French locale the accented characters are in their dictionary order for the string comparison.
:strnicoll is regarded as safer than strcoll, because it can help prevent buffer overflows (that could occur if a string is not null-terminated) if the n maximum number of characters is correctly to set to the size of the string memory buffers or less.
:The FM function strncoll is just a wrapper around the Microsoft-specific [https://docs.microsoft.com/en-us/cpp/c-runtime-library/reference/strnicoll-wcsnicoll-mbsnicoll-strnicoll-l-wcsnicoll-l-mbsnicoll-l _strnicoll] function.
