-ossl_cmp_log_parse_metadata() parses the given message buffer C<buf> populated
-by L<OSSL_CMP_log()> etc.
+ossl_cmp_log_parse_metadata() parses the given message buffer I<buf> populated
+by L<OSSL_CMP_log(3)> etc.
according to the pattern OSSL_CMP_LOG_START#level ": %s\n", filling in
-the variable pointed to by C<level> with the severity level or -1,
-the variable pointed to by C<func> with the function name string or NULL,
-the variable pointed to by C<file> with the file name string or NULL, and
-the variable pointed to by C<line> with the line number or -1.
-Any string returned via C<*func> and C<*file> must be freeed by the caller.

ossl_cmp_add_error_txt() appends text to the extra data field of the last
error message in the OpenSSL error queue, after adding the optional separator
L<ERR_print_errors_cb(3)>.
ossl_cmp_add_error_data() is a macro calling
-B<ossl_cmp_add_error_txt()> with the separator being ":".

ossl_cmp_add_error_line() is a macro calling
-B<ossl_cmp_add_error_txt()> with the separator being "\n".

ossl_cmp_asn1_octet_string_set1() frees any previous value of the variable
-referenced via the C<tgt> argument and assigns either a copy of
-the ASN1_OCTET_STRING given as the C<src> argument or C<NULL>.

It returns 1 on success, 0 on error.
