XOLINT(1)		     General Commands Manual		       XOLINT(1)

NAME
     xolint -- detect errors in programs using xo_emit(3)

SYNOPSIS
     xolint [-c] [-C <flags>] [-d] [-D] [-I] [-p] [-V] [-X] [files...]

DESCRIPTION
     xolint  is a tool for reporting common mistakes in format strings in source
     code that invokes xo_emit(3).  It allows these errors to  be  diagnosed  at
     build time, rather than waiting until runtime.

     xolint  takes one or more C files as arguments, and reports error, warning,
     or informational messages as needed.

     -c 	Invoke 'cpp' against the input file

     -C <flags>
		Flags that are passed to 'cpp'

     -d 	Enable debug output

     -D 	Generate documentation for all xolint messages

     -I 	Generate a table of xo_info_t structures.

     -p 	Print the offending lines after the error message is displayed

     -V 	Do not report errors, but instead print a complete list  of  all
		field  names,  sorted  alphabetically.	The output can help spot
		inconsistencies and spelling errors.

     -X 	Extract samples from xolint, suitable for internal testing.

     The output message contains the source filename and line number, the  class
     of  the  message,	the message, and, if -p is given, the line that contains
     the error:

	       % xolint -t xolint.c
	       xolint.c: 16: error: anchor format should be "%d"
	       16	  xo_emit("{[:/%s}");
