libevpq is a library that allows libevent based applications to communicate to a pgsql database in a non-blocking manner.

The goal of the project is to be easy to use along with transparent to the calling application as possible.

Utilizing within your application is simple:

1. initialize the configuration struct evpg_cfg *config; config = evpg_config_init();

2. Initialize libevent event_init();

3. Connect to your database one or more times for (i=0; i < number_of_connections; i++) evpg_connect(config, "dbname=whatever hostaddr=5.5.5.5")

4. Whenever a query needs to be made use evpg to make the query evpg_make_query(config, "SELECT FROM DB", (void )application_callback_when_query_is_finished, userdata);

   Argument 1 is the evpg configuration, Argument 2 is the query you would like to perform Argument 3 is the callback function to call once the query has completed. Argument 4 is a pointer to data the callback function should be passed.

5. Profit.

There are bugs, I'm sure of it - there isn't much error checking right now, but I am working on this.
