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 the -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. - -I have used sigprocmask() to block the reception of certain signals -while the program is executing SQL queries. This prevents a user -pressing Control-C from stopping all the back ends. It blocks SIGHUP, -SIGINT, and SIGTERM, but does not block SIGQUIT or obviously kill -9. -If your platform does not support sigprocmask(), you can remove those -function calls. ( Am I correct that abnormal termination can cause -shared memory resynchronization?) - -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. - -I am willing to maintain this if people find problems or want additional -functionality. - -Bruce Momjian (root@candle.pha.pa.us) |
