|GETC(3)||Library Functions Manual||GETC(3)|
get next character or word from input stream
function acts essentially identically to
but is a macro that expands in-line.
function obtains the next
int (if present) from the
stream pointed at by stream.
If successful, these routines return the next requested object
from the stream. If the stream is at end-of-file or a
read error occurs, the routines return
routines feof(3) and
ferror(3) must be used to
distinguish between end-of-file and error. If an error occurs, the global
variable errno is set to indicate the error. The
end-of-file condition is remembered, even on a terminal, and all subsequent
attempts to read will return
EOF until the condition
is cleared with
functions conform to ANSI X3.159-1989
getw() functions first appeared in
Version 1 AT&T UNIX;
getchar() in Version 2
AT&T UNIX; and
Version 7 AT&T UNIX.
Dennis Ritchie originally implemented
getw() in PDP-11
Since the size and byte order of an int may
vary from one machine to another,
getw() is not
recommended for portable applications.
