Then ran the program with no data written to the named pipe, it can still response to input of stdin, which seems like high priority sources will not block low priority sources. I go though the code of g_io_unix_prepare, it doen't simply return true. It seems that when creating a new type of GSource, I should take care of the *prepare* method, to prevent a very high priority source of this new type blocking other sources? -- Regards, - cee1
