GETC(3) Library Routines GETC(3)
fgetc, getc, getchar, getw - get next character or word from input
int fgetc (FILE *stream);
int getc (FILE *stream);
int getchar (void);
int getw (FILE *stream);
The fgetc function obtains the next input character (if present) from
the stream pointed at by stream, or the next character pushed back on
the stream via ungetc(3).
The getc function acts essentially identically to fgetc, but is a macro
that expands in-line.
The getchar function is equivalent to: getc with the argument stdin.
The getw 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 EOF. The 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
ferror(3), fread(3), fopen(3), putc(3), ungetc(3)
The fgetc, getc and getchar functions conform to ANSI/C.
Since EOF is a valid integer value, feof(3) and ferror(3) must be used
to check for failure after calling getw. The size and byte order of an
int varies from one machine to another, and getw is not recommended for
