Section (3) fgetws
fgetws — read a wide-character string from a FILE stream
fgetws() function is the
wide-character equivalent of the fgets(3) 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 null
wide character (L_zsingle_quotesz_ _zsingle_quotesz_). 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

already reached or if an error occurred, it returns NULL.
For an explanation of the terms used in this section, see attributes(7).
The behavior of

category of the current locale.
In the absence of additional information passed to the
fopen(3) call, it is
reasonable to expect that
fgetws() will actually read a multibyte
string from the stream and then convert it to a
This function is unreliable, because it does not permit to deal properly with null wide characters that may be present in the input.
