Function Details : wcscoll

intwcscoll(const wchar_t * ws1,const wchar_t * ws2) ;

Return Type : int

Integer type (typically 4 bytes, -2,147,483,648 to 2,147,483,647)
Read about return values of wcscoll function .

1st Parameter Type : const wchar_t *

A pointer to a read-only wide-character string, where each character is of type `wchar_t`. Used for representing text in wide-character encoding to support extended character sets, such as Unicode. The string is null-terminated, with the terminator being a `wchar_t` with value 0.

1st Parameter

Pointer to the first null-terminated wide-character string to be compared.

2nd Parameter Type : const wchar_t *

A pointer to a read-only wide-character string, where each character is of type `wchar_t`. Used for representing text in wide-character encoding to support extended character sets, such as Unicode. The string is null-terminated, with the terminator being a `wchar_t` with value 0.

2nd Parameter

Pointer to the second null-terminated wide-character string to be compared.

The wcscollfunction in C language Compares two wide character strings using the current locale's collation rules.
wcscoll compares the wide character string pointed to by s1 to the wide character string pointed to by s2, both interpreted as appropriate to the LC_COLLATE category of the current locale. It uses the collation rules specific to the current locale for the comparison, which can handle language-specific sorting rules.
The wcscollfunction takes 2 parameters:
  • •
    const wchar_t * `ws1`: Pointer to the first null-terminated wide-character string to be compared.
  • •
    const wchar_t * `ws2`: Pointer to the second null-terminated wide-character string to be compared.
Compares the wide-character strings `ws1` and `ws2` according to the current locale's collation rules. Returns an integer less than, equal to, or greater than zero if `ws1` is found to be less than, equal to, or greater than `ws2`, respectively. The comparison is locale-specific and may differ from a simple lexicographical comparison.
The wcscoll function return value :
  • Returns an integer less than, equal to, or greater than zero if s1 is found, respectively, to be less than, to match, or be greater than s2 according to the current locale's collation rules

Output

This example demonstrates the basic usage of wcscoll to compare two wide character strings using the current locale's collation rules.
