|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
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.
