- * Registers an event proc with the given PGconn.
- *
- * The same proc can't be registered more than once in a PGconn.  This
- * restriction is required because we use the proc address to identify
- * the event for purposes such as PQinstanceData().
- *
- * The name argument is used within error messages to aid in debugging.
- * A name must be supplied, but it needn't be unique.  The string is
- * copied, so the passed value needn't be long-lived.
- *
- * The passThrough argument is an application specific pointer and can be set
- * to NULL if not required.  It is passed through to the event proc whenever
- * the event proc is called, and is not otherwise touched by libpq.
- *
- * The function returns a non-zero if successful.  If the function fails,
- * zero is returned.
