EPERM No permission to set the scheduling policy and parameters specified in attr. Cincerly Niklas HoumanJanuary 12th, 2007, 07:14 PMhi there; I had a quick question, I ran the code and the error value of pthread_create is 12 at the time that it fails I searched Google with my best and couldn't find the answer. errno value set to 12 (ENOMEM) but needs to be EAGAIN.
