allocate_data

Description:

public static void allocate_data (Buffer buffer, uint payload_len, uint8 pad_len, uint8 csrc_count)

Allocate enough data in buffer to hold an RTP packet with csrc_count CSRCs, a payload length of payload_len and padding of pad_len.

buffer must be writable and all previous memory in buffer will be freed. If pad_len is >0, the padding bit will be set. All other RTP header fields will be set to 0/FALSE.

Parameters:

buffer	a Buffer
payload_len	the length of the payload
pad_len	the amount of padding
csrc_count	the number of CSRC entries
