In that a getc() is used to get the next character. The program hangs in this place indefinitely . The same program works fine on AIX and Solaris. Any ideas or pointers? What OS are you using? Sounds like getc() is blocking -- is it possible that another thread/process is locking the file you are trying to read? Kill the process with some signal that will generate a core dump and have a look. -- Andrew Bell andrew.bell.ia@xxxxxxxxx
