Function Documentation

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"

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

rpmverE()
