NAME
fgetws - read a wide-character string from a FILE stream SYNOPSIS
#include
wchart *fgetws(wchart *ws, int n, FILE *stream); DESCRIPTION The 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'\0'). 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 char‐ acters at ws. For a nonlocking counterpart, see unlockedstdio(3). RETURN VALUE The fgetws() function, if successful, returns ws. If end of stream was already reached or if an error occurred, it returns NULL. ATTRIBUTES For an explanation of the terms used in this section, see attributes(7). ┌──────────┬───────────────┬─────────┐ │Interface │ Attribute │ Value │ ├──────────┼───────────────┼─────────┤

C99, POSIX.1-2001. NOTES The behavior of fgetws() depends on the LCCTYPE category of the cur‐ rent 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 wide-character string. This function is unreliable, because it does not permit to deal prop‐ erly with null wide characters that may be present in the input. SEE ALSO fgetwc(3), unlockedstdio(3) COLOPHON
