sched_param

Structure that describes scheduling parameters

Synopsis:

#include <sched.h>

struct sched_param { 
    int32_t  sched_priority; 
    int32_t  sched_curpriority; 
    union { 
        int32_t  reserved[8]; 
        struct {    
            int32_t  __ss_low_priority;  
            int32_t  __ss_max_repl;  
            struct timespec     __ss_repl_period;   
            struct timespec     __ss_init_budget;   
        }           __ss;   
    }           __ss_un;    
}

#define sched_ss_low_priority   __ss_un.__ss.__ss_low_priority
#define sched_ss_max_repl       __ss_un.__ss.__ss_max_repl
#define sched_ss_repl_period    __ss_un.__ss.__ss_repl_period
#define sched_ss_init_budget    __ss_un.__ss.__ss_init_budget

Description:

You'll use the sched_param structure when you get or set the scheduling parameters for a thread or process.

You can use these functions to get the scheduling parameters:

• pthread_attr_getschedparam()
• pthread_getschedparam()
• sched_getparam()
• SchedGet()

You can use these functions to set the scheduling parameters:

• pthread_attr_setschedparam()
