Defined in header <wchar.h>
wchar_t* fgetws(wchar_t* str, int count, FILE* stream );		(since C95) (until C99)
wchar_t* fgetws(wchar_t*restrict str, int count, FILE*restrict stream );		(since C99)

Reads at most count -1 wide characters from the given file stream and stores them in str. The produced wide string is always null-terminated. Parsing stops if end-of-file occurs or a newline wide character is found, in which case str will contain that wide newline character.

Parameters

str	-	wide string to read the characters to
count	-	the length of str
stream	-	file stream to read the data from

Return value

str on success, a null pointer on an error
