sl@0: FUNCTION
sl@0: <<getc>>---read a character (macro)
sl@0: 
sl@0: INDEX
sl@0: 	getc
sl@0: 
sl@0: ANSI_SYNOPSIS
sl@0: 	#include <stdio.h>
sl@0: 	int getc(FILE *<[fp]>);
sl@0: 
sl@0: TRAD_SYNOPSIS
sl@0: 	#include <stdio.h>
sl@0: 	int getc(<[fp]>)
sl@0: 	FILE *<[fp]>;
sl@0: 
sl@0: DESCRIPTION
sl@0: <<getc>> is a macro, defined in <<stdio.h>>.  You can use <<getc>>
sl@0: to get the next single character from the file or stream
sl@0: identified by <[fp]>.  As a side effect, <<getc>> advances the file's
sl@0: current position indicator.
sl@0: 
sl@0: For a subroutine version of this macro, see <<fgetc>>.
sl@0: 
sl@0: RETURNS
sl@0: The next character (read as an <<unsigned char>>, and cast to
sl@0: <<int>>), unless there is no more data, or the host system reports a
sl@0: read error; in either of these situations, <<getc>> returns <<EOF>>.
sl@0: 
sl@0: You can distinguish the two situations that cause an <<EOF>> result by
sl@0: using the <<ferror>> and <<feof>> functions.
sl@0: 
sl@0: PORTABILITY
sl@0: ANSI C requires <<getc>>; it suggests, but does not require, that
sl@0: <<getc>> be implemented as a macro.  The standard explicitly permits
sl@0: macro implementations of <<getc>> to use the argument more than once;
sl@0: therefore, in a portable program, you should not use an expression
sl@0: with side effects as the <<getc>> argument.
sl@0: 
sl@0: Supporting OS subroutines required: <<close>>, <<fstat>>, <<isatty>>,
sl@0: <<lseek>>, <<read>>, <<sbrk>>, <<write>>.
