comment = "rpoll(3) interface for event-driven I/O"
desc = <<EOD
libbegemot provides rpoll(3), a simplified interface for handling event-driven
I/O programming.
Many programs need to read from several file descriptors at the same time.
Typically in these programs one of select(2) or poll(2) is used. These
calls are however clumsy to use and the usage of one of these calls is
probably not portable to other systems - not all systems support both calls.
The rpoll(3) family of functions is designed to overcome these restrictions.
They support the well known and understood technique of event driven
programming and, in addition to select(2) and poll(2) also support timers.
