Detailed Description

Rpm version comparison API.

Function Documentation

rpmverCmp()

int rpmverCmp	(	rpmver	v1,
		rpmver	v2 )

Compare two rpm version handles

Parameters

v1	1st version handle
v2	2nd version handle

Returns

0 if equal, -1 if v1 smaller, 1 if greater, than v2

rpmvercmp()

int rpmvercmp	(	const char *	a,
		const char *	b )

Segmented string compare for version or release strings.

Parameters

a	1st string
b	2nd string

Returns

+1 if a is "newer", 0 if equal, -1 if b is "newer"

rpmverE()

const char * rpmverE

(

rpmver

rv

)

Parameters

rv	rpm version handle

Returns

epoch portion

rpmverEVal()

uint32_t rpmverEVal

(

rpmver

rv

)

Parameters

rv	rpm version handle

Returns

numerical value of epoch

rpmverEVR()

char * rpmverEVR

(

rpmver

rv

)

Parameters

rv	rpm version handle

Returns

formatted [E:]V[-R] string (malloced)

rpmverFree()

rpmver rpmverFree

(

rpmver

rv

)

Free rpm version handle

Parameters

rv	rpm version handle

Returns

NULL always

rpmverNew()

rpmver rpmverNew	(	const char *	e,
		const char *	v,

Create new rpm version handle from e, v, r components

Parameters

e	epoch (or NULL)
v	version
r	release (or NULL)

Returns

rpm version, NULL on invalid

rpmverOverlap()

int rpmverOverlap	(	rpmver	v1,
		rpmsenseFlags	f1,

		rpmsenseFlags	f2 )

Determine whether two versioned ranges overlap.

Parameters

v1	1st version
f1	1st sense flags
v2	2nd version
f2	2nd sense flags

Returns

1 if ranges overlap, 0 otherwise

rpmverParse()

rpmver rpmverParse

(

const char *

evr

)

Parse rpm version handle from evr string

Parameters

evr	[epoch:]version[-release] string

Returns

rpm version, NULL on invalid evr

(

rpmver

rv

)

Parameters

rv	rpm version handle

Returns

version portion
