Subject: test/evp_test.c: distinguish parsing errors from processing errors
X-Git-Tag: openssl-3.0.0-alpha1~1549
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=f42c225d7f9a0bce0bf46103343402d3f0ad742f;p=oweals%2Fopenssl.git

test/evp_test.c: distinguish parsing errors from processing errors

Parsing functions are at liberty to return:

1:  when parsing on processing of the parsed value succeeded
0:  when the parsed keyword is unknown
-1: when the parsed value processing failed

Some parsing functions didn't do this quite right, they returned 0
when they should have returned -1, causing a message like this:

    Line 123: unknown keyword PeerKey

When this message (which is displayed when the parsing function
returns -1) would have been more appropriate:

    Line 123: error processing keyword PeerKey = ffdhe2048-2-pub
