Small library to run background processes with two way communication. Small and simple library to run processes in the background and communicate via the stdout, stderr and stdin file descriptors. The functionality of libtubo is similar to the glib function g_spawn_async_with_pipes() except that all pipe setup and monitoring is taken care of. The calling function only has to provide the functions with which to process the input/output of the remote process. The library first appeared in the year 2000 in the xfce3 desktop as part of the xfsamba application, and is now available for use for other developers.
