SPELIB Interface
SPELIB Sequence Rules
This subsection specifies the sequence considerations for the Pathway server and for
the SPELIB functions (and the equivalent SPELIB shell routines provided with the
sample Pathway server).
SP_SRV_ENCODE_INIT must be the first function called in the encoding process;
SP_SRV_ENCODE_END_PROC is the last. In between, a prescribed logical
sequence must be followed (for example, SP_SRV_ENCODE_ROW_DATA cannot
precede SP_SRV_ENCODE_ROW_DESCR).
Figure 5-4 illustrates the sequence required for issuing SPELIB encoding functions.
(The SP_SRV_ prefix has been removed from all of the function names in Figure 5-4
because of space limitations.)
