NAME

fgetws - read a wide character string from a FILE stream

SYNOPSIS

#include ws, int n, FILE *stream);

DESCRIPTION

The fgetws function is the wide-character equivalent of the fgets function. It reads a string of at most n-1 wide characters into the wide-character array pointed to by ws, and adds a terminating L'0' character. It stops reading wide characters after it has encountered and stored a newline wide character. It also stops when end of stream is reached.

The programmer must ensure that there is room for at least n wide characters at ws.

RETURN VALUE

The fgetws function, if successful, returns ws. If end of stream was already reached or if an error occurred, it returns NULL.

NOTES

The behaviour of fgetws depends on the LC_CTYPE category of the current locale.

In the absence of additional information passed to the fopen call, it is reasonable to expect that fgetws will actually read a multibyte string from the stream and then convert it to a wide character string.

This function is unreliable, because it does not permit to deal properly with null wide characters that may be present in the input.
