Each call returns a structure or -value, so if you need to do more work with the result, you can. Also, I -have a global variable that allows you to disable the error checking I -have added to the doquery() routine. - -I have added a function called fetch(), which allows you to pass -pointers as parameters, and on return the variables are filled with data -from the binary cursor you opened. These binary cursors are not useful -if you are running the query engine on a system with a different -architecture than the database server. If you pass a NULL pointer, the -column is skipped, and you can use libpq to handle it as you wish. - -There are two functions, get_result() and set_result(), that allow you -to handle multiple result sets at the same time. - -There is a reset_fetch() that starts the fetch back at the beginning. - -There is a demo program called pginsert that demonstrates how the -library can be used. - You can create a library of pginterface.c and halt.c, and just include pginterface.h in your source code.
