Detailed Description

Macro Definition Documentation

◆ PJ_STUN_ERROR_RESPONSE_BIT

#define PJ_STUN_ERROR_RESPONSE_BIT (0x0110)

The error response bit in the message type.

◆ PJ_STUN_GET_CH_NB

#define PJ_STUN_GET_CH_NB ( u32 ) ((pj_uint16_t)(u32>>16))

Get 16bit channel number from 32bit integral value. Note that uint32 attributes are always stored in host byte order after they have been parsed from the PDU, so no need to do ntohs() here.

◆ PJ_STUN_GET_METHOD

#define PJ_STUN_GET_METHOD ( msg_type ) ((msg_type) & 0xFEEF)

Retrieve the STUN method from the message-type field of the STUN message.

◆ PJ_STUN_GET_RT_PROTO

#define PJ_STUN_GET_RT_PROTO ( u32 ) (u32 >> 24)

Get protocol value from 32bit TURN REQUESTED-TRANSPORT attribute.

◆ PJ_STUN_INDICATION_BIT

#define PJ_STUN_INDICATION_BIT (0x0010)

The error response bit in the message type.

◆ PJ_STUN_IS_ERROR_RESPONSE

#define PJ_STUN_IS_ERROR_RESPONSE ( msg_type ) (((msg_type) & 0x0110) == 0x0110)

Determine if the message type is an error response.

◆ PJ_STUN_IS_INDICATION

#define PJ_STUN_IS_INDICATION ( msg_type ) (((msg_type) & 0x0110) == 0x0010)

Determine if the message type is an indication message.

◆ PJ_STUN_IS_REQUEST

#define PJ_STUN_IS_REQUEST ( msg_type ) (((msg_type) & 0x0110) == 0x0000)

Determine if the message type is a request.

◆ PJ_STUN_IS_RESPONSE

#define PJ_STUN_IS_RESPONSE ( msg_type ) (((msg_type) & 0x0100) == 0x0100)

Determine if the message type is a response.

◆ PJ_STUN_IS_SUCCESS_RESPONSE

◆ PJ_STUN_SET_CH_NB

#define PJ_STUN_SET_CH_NB ( chnum ) (((pj_uint32_t)chnum) << 16)

Convert 16bit channel number into 32bit integral value. Note that uint32 attributes will be converted to network byte order when the attribute is written to packet, so no need to do htons() here.

◆ PJ_STUN_SET_RT_PROTO

#define PJ_STUN_SET_RT_PROTO ( proto ) (((pj_uint32_t)(proto)) << 24)

Convert protocol value to be placed in 32bit TURN REQUESTED-TRANSPORT attribute.

If application wants to apply credential to the message, it MUST include a blank MESSAGE-INTEGRITY attribute in the message as the last attribute or the attribute before FINGERPRINT. This function will calculate the HMAC digest from the message using the supplied key in the parameter. The key should be set to the password if short term credential is used, or calculated from the MD5 hash of the realm, username, and password using pj_stun_create_key() if long term credential is used.

If FINGERPRINT attribute is present, this function will calculate the FINGERPRINT CRC attribute for the message. The FINGERPRINT MUST be added as the last attribute of the message.

Parameters

msg	The STUN message to be printed. Upon return, some fields in the header (such as message length) will be updated.
pkt_buf	The buffer to be filled with the packet.
buf_size	Size of the buffer.
options	Options, which currently must be zero.
key	Authentication key to calculate MESSAGE-INTEGRITY value. Application can create this key by using pj_stun_create_key() function.
