I have spawned a couple of threads and they are dumping all the error messages on the screen like a maniac and giving me a headache. Some help would be highly appreciated. Thanks.

For a multiplatform solution, I suggest that you try to use the class Popen in [url=http://code.activestate.com/recipes/440554/]this activestate recipe[/url]. It contains a very sophisticated solution. See if it applies to your problem. Re: segmentation fault on fprintf to stderr after modulo 13 Years Ago by gerard4143 How is MOLNUMBER defined? Re: segmentation fault on fprintf to stderr after modulo 13 Years Ago by edbarker [QUOTE=gerard4143;1305061]How is MOLNUMBER defined?[/QUOTE] it is an integer (int MOLNUMBER;), which as a variable i use globally i put it in capitals (probably not good practice) I don't #define it as a constant. It is set after reading the molecule's entry number from the file. Re: printing stderr ouput ... 13 Years Ago by manojwali Try to use fflush() function. May be that will solve your problem. -Manoj Re: printing stderr ouput ... 13 Years Ago by rahul8590 no it doesnt .. Re: printing stderr ouput ... 13 Years Ago by manojwali use flushall() instead of that. Re: printing stderr ouput ... 13 Years Ago by Narue flushall isn't guaranteed to be available as it's a non-standard extension. Besides, you can achieve the same effect as flushall (assuming it does what one might expect) with fflush(NULL).
