Function Documentation

unsigned int MSG_configure

(

void

)

Configure and start the MSG task.

Return values:

	MSG_ALOCFAIL	Fixed packet allocator (FPA) buffer allocation failed
	MSG_BADSTATE	Cannot initialize in the current MSG state
	MSG_CFGNTFND	Configuration database not found
	MSG_FINDFAIL	Cannot look up up alternate messages in database
	MSG_FORKFAIL	FORK initialization failed
	MSG_FPAGFAIL	Fixed packet allocator get failed during task start
	MSG_FPAIFAIL	Fixed packet allocator (FPA) initialization failed
	MSG_MUALOCFL	Cannot allocate a mutex
	MSG_PKT2FEW	Packet count parameter too small
	MSG_PKT2SMAL	Packet length parameter too small
	MSG_SUCCESS	Success

MSG_configure() configures MSG. It reads configuration database files to perform the MSG_initialize(), MSG_attachOutputRtn() and MSG_startTask() functions. If the configuration databases can't be found, MSG will still do its best to start up a message task based on an internal default configuration.
