Memory management functions for messages

Function Documentation

struct lp_msg* msg_allocator_alloc ( unsigned payload_size )

Allocate a new message with given payload size.

Parameters

payload_size the size in bytes of the requested message payload

Since this module relies on the member lp_msg.pl_size (see msg_allocator_free()), it has writing responsibility on it.

void msg_allocator_free ( struct lp_msg * msg )

Free a message.

Parameters

msg	a pointer to the message to release

void msg_allocator_free_at_gvt ( struct lp_msg * msg )

Free a message after its destination time is committed.

Parameters

msg	a pointer to the message to release

void msg_allocator_on_gvt ( simtime_t current_gvt )

Free the committed messages after a new GVT has been computed.

Parameters

current_gvt the latest value of the GVT
