fgetws -- get a line of wide characters from a stream
Standard C Library (libc, -lc)
fgetws(wchar_t * restrict ws, int n, FILE * restrict fp);
The fgetws() function reads at most one less than the number of characters specified by n
from the given fp and stores them in the wide-character string ws. Reading stops when a
newline character is found, at end-of-file or error. The newline, if any, is retained. If
any characters are read and there is no error, a '\0' character is appended to end the
Upon successful completion, fgetws() returns ws. If end-of-file occurs before any charac-
ters are read, fgetws() returns NULL and the buffer contents remain unchanged. If an error
occurs, fgetws() returns NULL and the buffer contents are indeterminate. The fgetws() func-
tion does not distinguish between end-of-file and error, and callers must use feof(3) and
ferror(3) to determine which occurred.
[EBADF] The given fp argument is not a readable stream.
[EILSEQ] The data obtained from the input stream does not form a valid multibyte
The function fgetws() may also fail and set errno for any of the errors specified for the
routines fflush(3), fstat(2), read(2), or malloc(3).

The fgetws() function conforms to IEEE Std 1003.1-2001 (``POSIX.1'').
