Function Documentation

static int cmpArgvStr	(	rpmts	ts,
		const char *	lname,
		const char **	AV,
		int	AC,
		const char *	B
	)			`[static]`

Search for string B in argv array AV.

Parameters:

	ts	transaction set
	lname	type of link
	AV	argv array
	AC	no. of args
	B	string

Returns:: 1 if found, 0 not found, -1 error

static int findErases	(	rpmts	ts,
		rpmte	p,
		unsigned	thistid,
		IDT	ip,
		int	niids
	)			`[static]`

Find (and add to transaction set) all erase elements with matching blink.

In addition, recreate any added transaction element linkages.

XXX rp->h should have FLINK{HDRID,PKGID,NEVRA} populated. XXX ip->h should have BLINK{HDRID,PKGID,NEVRA} populated. XXX p = ts->teInstall is added transaction element from rp->h.

Parameters:

	ts	transaction set (ts->teInstall set to last added pkg)
	p	most recently added install element (NULL skips linking)
	thistid	current transaction id
	ip	currently installed package(s) to be erased
	niids	no. of currently installed package(s)

Returns:: -1 on error, otherwise no. of erase elemnts added
