How to use pthread_setschedparam

vijaya_svk · 02-15-2008, 01:35 AM

Hi
I am facing problems in using pthread_setschedparam()

For the policies
SCHED_FIFO and SCHED_RR
i am getting the
error : operation not permitted
for SCHED_OTHER the error is ----invalid argument

I am unable to set parameters.

Please help in this issue.

I am using FEDORA 8 and GCC 4.1 versions.

It might be useful for you to do man pthread_setschedparam at a command-line.

"Operation not permitted" corresponds to an EPERM error-code, whereas "invalid argument" is EINVAL.

This is a POSIX written-by-committee error message, so you'll have to excuse the pontificating use of the word "shall" in the text of that man-page.
