Include dependency graph for version.h:

This graph shows which files directly or indirectly include this file:

Data Structures
struct	dpkg_version
	Data structure representing a Debian version. More...

Macros
#define	DPKG_VERSION_OBJECT(e, v, r) (struct dpkg_version){ .epoch = (e), .version = (v), .revision = (r) }
	Compound literal for a dpkg_version.

#define	DPKG_VERSION_INIT DPKG_VERSION_OBJECT(0, NULL, NULL)

Functions
void	dpkg_version_blank (struct dpkg_version *version)
	Turn the passed version into an empty version.

bool	dpkg_version_is_informative (const struct dpkg_version *version)
	Test if a version is not empty.

int	dpkg_version_compare (const struct dpkg_version a, const struct dpkg_version b)
	Compares two Debian versions.

bool	dpkg_version_relate (const struct dpkg_version a, enum dpkg_relation rel, const struct dpkg_version b)
	Check if two versions have a certain relation.

Variables
enum DPKG_ATTR_ENUM_FLAGS	dpkg_relation
	Enum constants for the supported relation operations that can be done on Debian versions.

	DPKG_RELATION_NONE = 0
	The “none” relation, sentinel value.

	DPKG_RELATION_EQ = DPKG_BIT(0)
	Equality relation (‘=’).

	DPKG_RELATION_LT = DPKG_BIT(1)
	Less than relation (‘<<’).

	DPKG_RELATION_LE = DPKG_RELATION_LT \| DPKG_RELATION_EQ
	Less than or equal to relation (‘<=’).

	DPKG_RELATION_GT = DPKG_BIT(2)
	Greater than relation (‘>>’).

	DPKG_RELATION_GE = DPKG_RELATION_GT \| DPKG_RELATION_EQ
	Greater than or equal to relation (‘>=’).
