How to Load table from client file in C?

Hi all,

I'm trying to determine how to write a C program to load a client file with the "load table ... using client file..." syntax without calling out to the dbisql program to load the table.  I'm probably not seeing the forest for the trees here.  I know I can use the bulk api (equivalent of bcp) but would rather use the load table because it is much faster.
