NAME
src2man - extract man pages from source files. SYNOPSIS
src2man [-n][-d date][-v volume][-r release] [srcfile ...] DESCRIPTION
src2man scans source file srcfile. Only C source files are supported for now. Comments blocks starting by "/** num", where num is a section number, are converted into a man file, using txt2man(1). The first line of the comment block must contain the name of the manpage, usually the function name, followed by a "-" and a short description. The following lines are the "DESCRIPTION" section content, except if they are in upper case, in which case they define a new sec- tion. If the next line after a comment block is empty, Then no "SYNOPSIS" section will be generated. Otherwise, src2man will look in the follow- ing source lines for a function prototype or a type definion (struct, union, typedef, ...) matching the manpage name, and include it in a "SYNOPSIS" section. This avoids to duplicate the type or function prototype in the comment block. The best place for code documentation is in the source file, where the body is implemented, not the header file which only contains the prototype. src2man automatically searches for the presence of a prototype in the corresponding header file, and if found, will print a "#include" statement in the synopsis. OPTIONS
-d date Set the date of the man pages. Defaults to current date. -n No man page is created. The name of the manpages that would be created are printed. -v volume Specify the name of the volume to be printed in center header of generated manpages. -r release Specify the project name and release number for the generated manpage. EXAMPLE
The following example displays C code and comments to generate a manpage foobar.3: /** 3 * foobar - a sample dummy function * This line is now the first of the description section. * Note that function parameters parm1 and parm2 are highlighted * in the generated man page. */ int foobar(char *parm1, int parm2) { ... return 0; } SEE ALSO
