Can CFE_SB_AllocateMessageBuffer fail?

[irowebbn]

CFE_SB_AllocateMessageBuffer has no way to indicate an error. Can it ever return a null pointer, or can we assume any pointer it returns is safe for use?

The answer is yes, CFE_SB_AllocateMessageBuffer can return NULL. See https://github.com/nasa/cFE/blob/ee187426d08e0d4f0edf640d07381b8f676be8d3/modules/sb/fsw/src/cfe_sb_api.c#L2004
