[OMPI devel] "prefix" style guideline

[Eugene Loh]

In https://svn.open-mpi.org/trac/ompi/wiki/CodingStyle , there is 
mention of "the prefix rule."  What is this rule?

Let me ask specifically this.  If I look at 
https://svn.open-mpi.org/source/xref/ompi_1.3/ompi/mca/btl/sm/btl_sm_endpoint.h#46 
, I see a declaration for "void btl_sm_add_pending".  Should that really 
have an "mca_" appended to the name?  Don't worry about the 
particulars.  I'm about to change this code.  I'm just asking about the 
principles.  Because this function is callable from a file other than 
where it is defined, should the prefix be "mca_btl_sm_" or does 
"btl_sm_" suffice?

Similarly, I see a btl_sm_pending_send_item_t type.  Should that also 
have mca_ appended?

Ouch, and this one:  sm_fifo_t.  (This one is my fault.)  I assume it 
should be mca_btl_sm_fifo_t, yes?

P.S.  Shouldn't the "prefix rule" be explained in the "coding style" 
twiki page?
