Defined in header <wchar.h> int wcsncmp( const wchar_t* lhs, const wchar_t* rhs, size_t count ); (since C95) Compares at most count wide characters of two null-terminated wide strings. The comparison is done lexicographically. Parameters lhs, rhs - pointers to the null-terminated wide strings to compare count - maximum number of characters to compare Return value Negative value if lhs is less than rhs. ​0​ if lhs is equal to rhs. Positive value if lhs is

Defined in header <wchar.h> size_t wcsftime( wchar_t* str, size_t count, const wchar_t* format, tm* time ); (since C95) Converts the date and time information from a given calendar time time to a null-terminated wide character string str according to format string format. Up to count bytes are written. Parameters str - pointer to the first element of the wchar_t array for output count - maximum number of wide characters to write format - pointer to a nul

Defined in header <wchar.h> size_t wcscspn( const wchar_t* dest, const wchar_t* src ); (since C95) Returns the length of the maximum initial segment of the wide string pointed to by dest, that consists of only the characters not found in wide string pointed to by src. Parameters dest - pointer to the null-terminated wide string to be analyzed src - pointer to the null-terminated wide string that contains the characters to search for Return value The leng

Defined in header <wchar.h> int wcscoll( const wchar_t *lhs, const wchar_t *rhs ); (since C95) Compares two null-terminated wide strings according to the collation order defined by the LC_COLLATE category of the currently installed locale. Parameters lhs, rhs - pointers to the null-terminated wide strings to compare Return value Negative value if lhs is less than (precedes) rhs. ​0​ if lhs is equal to rhs. Positive value if lhs is greater than (follows) rhs.

Defined in header <wchar.h> int wcscmp( const wchar_t *lhs, const wchar_t *rhs ); (since C95) Compares two null-terminated wide strings lexicographically. The sign of the result is the sign of the difference between the values of the first pair of wide characters that differ in the strings being compared. The behavior is undefined if lhs or rhs are not pointers to null-terminated wide strings. Parameters lhs, rhs - pointers to the null-terminated wide strings to com

Defined in header <wchar.h> wchar_t* strchr( const wchar_t* str, wchar_t ch ); (since C95) Finds the first occurrence of the wide character ch in the wide string pointed to by str. Parameters str - pointer to the null-terminated wide string to be analyzed ch - wide character to search for Return value Pointer to the found character in str, or NULL if no such character is found.
