Discards any whitespace characters (as identified by calling isspace()) until the first non-whitespace character is found,

Discards any whitespace characters (as identified by calling isspace()) until the first non-whitespace character is found, then takes as many characters as possible to form a valid base-n (where n=base) integer number

Defined in header <wchar.h> size_t wcsspn( 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 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 length of

Defined in header <wchar.h> wchar_t* wcsrchr( const wchar_t* str, wchar_t ch ); (since C95) Finds the last 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.

Defined in header <wchar.h> wchar_t* wcsstr( const wchar_t* dest, const wchar_t* src ); (since C95) Finds the first occurrence of the wide string src in the wide string pointed to by dest. The terminating null characters are not compared.
