dpkg_options_parse_pkgname()

struct pkginfo * dpkg_options_parse_pkgname	(	const struct cmdinfo *	cmd,
		const char *	name
	)

Parse an argument as a package name.

The string is parsed as a singleton package name, and a pkginfo instance is returned.

Parameters

cmd	The command information structure currently parsed.
name	The package name argument

Returns

A package instance.
