Function Documentation

dba_err bufrex_dtable_create	(	const char *	id,
		bufrex_dtable *	table
	)

Create a new bufrex_dtable structure.

Return values:

table

The bufrex_dtable structure that can be used to access the table. It is a pointer to a local shared cache that is guaranteed to live until the end of the program, and it does not need to be deallocated.

Returns:

The error status (See error.h)

dba_err bufrex_dtable_query	(	bufrex_dtable	table,
		dba_varcode	var,
		bufrex_opcode *	res
	)

Query the bufrex_dtable.

Parameters:

	table	bufrex_dtable to query
	var	entry code (i.e. DXXYYY as a dba_varcode DBA_VAR(3, xx, yyy).
	res	the bufrex_opcode chain that contains the expansion elements (must be deallocated by the caller using bufrex_opcode_delete)

Returns:

The error status (See error.h)
