ROUTINE NAME : CAN_Transmit_request

INPUT/OUTPUT : pointer on the CAN buffer to send/error status

DESCRIPTION : Puts a message into the queue, and may request an immediate

!!!This function MUST NOT be interrupted, so protect it with SIM and RIM

statements

when used OUTSIDE the notification fuctions of CAN_custom.c!!!
