fgetc, fgets, getc, getchar, ungetc - input of characters and strings
fgetc() reads the next character from
stream and returns it as an
unsigned char cast to an
int, or EOF on end of file or error.
fgets() reads in at most one less than
stream and stores them into the buffer pointed
s. Reading stops after an EOF or a
newline. If a newline is read, it is stored into the buffer. A
terminating null byte ('\0') is stored after the last character in the
c back to
unsigned char, where it is available for subsequent
read operations. Pushed-back characters will be returned in reverse
order; only one pushback is guaranteed.
Calls to the functions described here can be mixed with each other
and with calls to other input functions from the
for the same input stream.
For nonlocking counterparts, see unlocked_stdio(3).
POSIX.1-2001, POSIX.1-2008, C89, C99.
It is not advisable to mix calls to input functions from the
stdio library with low-level calls to read(2)
for the file descriptor associated with the input stream; the results
will be undefined and very probably not what you want.
