wcscoll() function in C++ compares two null-terminated string. The comparison is based on the current locale defined by the LC_COLLATE category.
This function starts comparing the first character of each string. They are considered as equal until the characters differ or until a null wide character signaling the end of a string is reached.
int wcscoll( const wchar_t* wcs1, const wchar_t* wcs2 )
Parameters: The function accepts two mandatory parameters which are described below:
- wcs1: It is a pointer to the null terminated wide strings to compare.
- wcs2: It is a pointer to the null terminated wide strings to compare.
Return value : The function returns three value as below:
- 0, if values indicates that both strings are equal.
- Positive value, if the first character that is different in wcs1 is greater than the corresponding character in wcs2.
- Negative value, if the first character that is different in wcs1 is less than the corresponding character in wcs2.
