Hi, This is offtopic for this list. from http://gcc.gnu.org/lists.html "gcc-help is a relatively high volume list for people searching for help in building or using GCC." Anyway, for your question... i see few problems 1. struct sched_param *p; sched_getparam(0,p); Using unallocated memory. will result in SEGV 2. When you get 1 corrected, you may get another error >From man 2 sched_setscheduler <snip> EPERM The calling process does not have appropriate privileges. <snip> On Sun, 26 Sep 2004, Ankit Jain wrote: > hi > > /* soft realtime scheduling variable */ > struct sched_param *p; > > > /* set soft real-time scheduling */ > sched_getparam(0,p); > p->sched_priority = 50; > if (sched_setscheduler(0,SCHED_FIFO,p)) > fprintf(stderr,"Could not change scheduler > settings\n"); > > if anyone knows about this then i need some help > > p is a pointer to the structure sched_param which is > defined in sched.h > > this structure has a variable __sched_priority where i > have to set the priority of the process > > p->sched_priority =50 this line gives a segmentation > fault. > how t oaccess this variable (__sched_priority) of the > header file > > thanks > > ankit > > ________________________________________________________________________ > Yahoo!
