<p>This function searches a credential cache for credentials matching <em>mcreds</em> and returns it if found.</p>
<p>Valid values for <em>flags</em> are:</p>
<blockquote>
<div><blockquote>
<div><ul class="simple">
<li><p>#KRB5_TC_MATCH_TIMES The requested lifetime must be at least as great as in <em>mcreds</em> .</p></li>
<li><p>#KRB5_TC_MATCH_IS_SKEY The <em>is_skey</em> field much match exactly.</p></li>
<li><p>#KRB5_TC_MATCH_FLAGS Flags set in <em>mcreds</em> must be set.</p></li>
<li><p>#KRB5_TC_MATCH_TIMES_EXACT The requested lifetime must match exactly.</p></li>
<li><p>#KRB5_TC_MATCH_FLAGS_EXACT Flags must match exactly.</p></li>
<li><p>#KRB5_TC_MATCH_AUTHDATA The authorization data must match.</p></li>
<li><p>#KRB5_TC_MATCH_SRV_NAMEONLY Only the name portion of the principal name must match, not the realm.</p></li>
<li><p>#KRB5_TC_MATCH_2ND_TKT The second tickets must match.</p></li>
<li><p>#KRB5_TC_MATCH_KTYPE The encryption key types must match.</p></li>
<li><p>#KRB5_TC_SUPPORTED_KTYPES Check all matching entries that have any supported encryption type and return the one with the encryption type listed earliest.</p></li>
