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 string.
fgetws() returns ws. If end-of-file occurs before any characters are read,
NULLand the buffer contents remain unchanged. If an error occurs,
NULLand the buffer contents are indeterminate. The
fgetws() function does not distinguish between end-of-file and error, and callers must use feof(3) and ferror(3) to determine which occurred.
fgetws() function conforms to IEEE Std 1003.1-2001 (“POSIX.1”).
