Member Function Documentation

Parse() [1/2]

int Dwm::OptArgs::Parse	(	int	argc,
		char *	argv[] )

Parses all optional arguments.

Returns the next argument index, which the caller should compare against argc. If parsing fails, will emit a usage statement and exit.

Parse() [2/2]

int Dwm::OptArgs::Parse	(	int	argc,
		const std::string	argv[] )

Parses all optional arguments.

Returns the next argument index, which the caller should compare against argc. If parsing fails, will emit a usage statement and exit.
