Are you talking about package files or installed packages from the
local RPMDB? The procedure is different for each one, but once you
have a "Header" object for the package in question, use something
like
this to get the name, version, etc.:
char *N, *E, *V, *R, *A;
Note that headerNEVRA() does not actually return the Epoch:.
E = NULL;
headerNEVRA(hdr, (const char **) &N, (const char **) &E,
(const char **) &V, (const char **) &R,
(const char **) &A);
printf("Package: %s (%s:%s-%s) for %s\n", N, ((E)?(E):("0")),
V, R, A);
headerFreeData(N, RPM_STRING_TYPE);
headerFreeData(E, RPM_STRING_TYPE);
headerFreeData(V, RPM_STRING_TYPE);
headerFreeData(R, RPM_STRING_TYPE);
headerFreeData(A, RPM_STRING_TYPE);
NEVRA, now I get it :) That is what I was looking for. However,
your snippets combined with Jeff's snippets don't work:
Hint: Using data structures other than Header is recommended, headers
are way too bloaty
to be used as the primary data structure for rpm (or anything using
rpmlib).
E.g.
ds = rpmdsThis(h, RPMTAG_PROVIDENAME, RPMSENSE_EQUAL);
fprintf(stdout, "%s\n", rpmdsDNEVR(ds)+2);
ds = rpmdsFree(ds);
is perhaps terser (but lacks the arch, and os, and ...).
headerSprintf() is the fastest and most convenient if you want
strings from headers.
