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

Referenced by findErases().

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
