FGETWS(3) Linux Programmer's Manual FGETWS(3) NAME fgetws - read a wide-character string from a FILE stream SYNOPSIS #include <wchar.h> wchar_t *fgetws(wchar_t *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 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 char- acters at ws. For a nonlocking counterpart, see unlocked_stdio(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. CONFORMING TO C99, POSIX.1-2001. NOTES The behavior of fgetws() depends on the LC_CTYPE 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.
