getchar
OS/161 Reference Manual
Name
getchar - read character from standard input
Library
Standard C Library (libc, -lc)
Synopsis
#include <stdio.h>
int
getchar(void);
Description
getchar reads a single character from standard input. The character is
converted to unsigned char before being returned; thus, EOF, which is
negative, is not a possible successful return value.
Return Values
On success, getchar returns the character read. On error, or end of
file, EOF is returned.
Errors
Any of the errors associated with read
may occur.
