** File: cfe_sb_api.c
**
** Purpose:
** This file contains the source code for the SB API's.
**
** Notes: The following 4 terms have been, or are used in the cFS architecture and implementation
**
** StreamId - First 16 bits of CCSDS Space Packet Protocol (SPP) 133.0-B.1c2 Blue Book
** packet primary header. It contains the 3 bit Version Number, 1 bit Packet Type ID,
** 1 bit Secondary Header flag, and 11 bit Application Process ID
** It was used in earlier cFS implementaions and is defined here for historical reference
** It is NOT exposed to user applications.
**
** MsgId - Unique numeric message identifier within a mission namespace. It is used by cFS
** applications to the identify messages for publishing and subscribing
** It is used by the SB API and encoded in a mission defended way in the header of
** all cFS messages.
** It is exposed to all cFS applications
**
** ApId - CCSDS Application Process Id field in the primary header.
** It has default bit mask of 0x07FF and is part of the cFS message Id
** It should not be confused with the cFE Executive Services (ES) term appId which
** identifies the software application/component
** It is NOT exposed to user applications.
**
** MsgIdkey - This is a unique numeric key within a mission namespace that is used with
** cFS software bus internal structures.
** It is algorithmically created in a mission defined way from the MsgId to support
** efficient lookup and mapping implementations
** It is NOT exposed to user applications.
