#include <sip.h>

const struct sip_xaction *sip_get_trans(sip_msg_t sip_msg, int which,
 int *error);
DESCRIPTION

The sip_get_trans() function matches a transaction to a message as specified in RFC 3261, sections 17.1.3 and 17.2.3. The sip_get_trans() function holds a reference to the returned transaction. The caller must release this reference after use.

RETURN VALUES

The sip_get_trans() function returns the required value on success or NULL on failure.

The value of errno is not changed by these calls in the event of an error.

ERRORS

On success, the value of the location pointed to by error is set to 0.
