ENUM Resolution Support
Sample Code
The following code sample illustrates an implementation of the ENUM callback
using an abstract function that which performs regular expression parsing, called
AppRegComp.
/*==========================================================================*/
RvStatus AppRegExpResolutionNeeded EvHandler (
IN RvSipTransmitterMgrHandle hTrxMgr,
IN void* pAppTrxMgr,
IN RvSipTransmitterHandle hTrx,
IN RvSipAppTransmitterHandle hAppTrx,
INOUT RvSipTransmitterRegExpResolutionParams* pRegExpParams)
{
RvStatus rv = RV_OK;
RvInt32 index;
RvSipTransmitterRegExpMatch *pCurrMatch;
rv = AppRegComp(
pRegexpParams->strRegExp, /* A regular expression from NAPTR query */
pRegexpParams->strString, /* The string to apply the regexp on */
pRegexpParams->matchSize, /* The size of the pMatches array */
pRegexpParams->eFlags, /* regexp parsing flags */
pRegexpParams->pMatches); /* Array of matching substrings offsets, any unused*/
/* array elements contain -1 offset */
for (index =0, pCurrMatch = pRegexpParams->pMatches;
index < pRegexpParams->matchSize && pCurrMatch-> startOffSet != -1;
index++, pCurrMatch++)
{
printf("Found match from %d to %d",
pCurrMatch-> startOffSet, pCurrMatch-> endOffSet);
}
return rv;
}
