cpp

CPP(1)							      General Commands Manual							    CPP(1)

NAME

       cpp - C language preprocessor

SYNOPSIS

       cpp [ option ...  ] [ ifile [ ofile ] ]

DESCRIPTION

       Cpp  interprets ANSI C preprocessor directives and does macro substitution.  The input ifile and output ofile default to standard input and
       standard output respectively.

       The options are:

       -Dname
       -Dname=def
       -Idir  Same as in 2c(1).

       -M     Generate no output except a list of include files in a form suitable for specifying dependencies to mk(1).  Use twice to list  files
	      in angle brackets.

       -N     Turn  off  default include directories.  All must be specified with -I.  Without this option, /$objtype/include and /sys/include are
	      used as the last two searched directories for include directives, where $objtype is read from the environment.

       -V     Print extra debugging information.

       -+     Understand C++ comments.

       The output file contains processed text sprinkled with lines that show the original input line numbering:

	      #line linenumber "ifile"

       The input language is as described in the ANSI C standard.  The C compilers do not use cpp; they contain their own simple but adequate pre-
       processor, so cpp is usually superfluous.

FILES

       /sys/include
	      directory for machine-independent include files

       /$objtype/include
	      directory for machine-dependent include files

SOURCE

       /sys/src/cmd/cpp
