unifdef

unifdef(1)							   User Commands							unifdef(1)

NAME

       unifdef - resolve and remove ifdef'ed lines from C program source

SYNOPSIS

       unifdef [-clt] [-Dname] [-Uname] [-iDname] [-iUname] ...
	    [filename]

DESCRIPTION

       unifdef	removes  ifdefed lines from a file while otherwise leaving the file alone. It is smart enough to deal with the nested ifdefs, com-
       ments, single and double quotes of C syntax, but it does not do any including or interpretation of macros. Neither does it strip  out  com-
       ments, though it recognizes and ignores them. You specify which symbols you want defined with -D options, and which you want undefined with
       -U options. Lines within those ifdefs will be copied to the output, or removed, as appropriate. Any ifdef, ifndef, else,  and  endif  lines
       associated with filename will also be removed.

       ifdefs involving symbols you do not specify are untouched and copied out along with their associated ifdef, else, and endiff1 lines.

       If an ifdefX occurs nested inside another ifdefX, then the inside ifdef is treated as if it were an unrecognized symbol. If the same symbol
       appears in more than one argument, only the first occurrence is significant.

       unifdef copies its output to the standard output and will take its input from the standard input if no filename argument is given.

OPTIONS

       The following options are supported:

       -c	  Complement the normal operation. Lines that would have been removed or blanked are retained, and vice versa.

       -l	  Replace ``lines removed'' lines with blank lines.

       -t	  Plain text option. unifdef refrains from attempting to recognize comments and single and double quotes.

       -Dname	  Lines associated with the defined symbol name.

       -Uname	  Lines associated with the undefined symbol name.

       -iDname	  Ignore, but print out, lines associated with the defined symbol name. If you use ifdefs to delimit non-C lines, such as comments
		  or  code which is under construction, then you must tell unifdef which symbols are used for that purpose so that it will not try
		  to parse for quotes and comments within them.

       -iUname	  Ignore, but print out, lines associated with the undefined symbol name.

EXIT STATUS

       The following exit values are returned:

       0    Successful operation.

       1    Operation failed.
