priocntlset(2) System Calls Manual priocntlset(2)
NAME
priocntlset - change scheduling property of a process or set of
processes
SYNOPSIS
#include <sys/types.h> #include <sys/procset.h> #include <sys/prioc-
ntl.h> #include <sys/rtpriocntl.h> #include <sys/tspriocntl.h>
datatype priocntlset (
proceset_t *psp,
int cmd,
.
.
.
/*arg*/ );
PARAMETERS
Specifies a pointer to a structure. The type of structure depends on
the value you select for the cmd parameter. Specifies the functions to
be performed. Specifies a pointer to a procset structure.
DESCRIPTION
This function is used to change the scheduling properties of a running
process or group of processes. While the priocntl(2) function performs
the same tasks, this function enables you to specify the process or set
of processes that will change in a less complicated manner.
How the process changes depends on the value you select for the cmd pa-
rameter. The value of the arg parameter is dependent on the value you
select for the cmd parameter. See the priocntl function for detailed
information on these parameters.
The psp parameter enables you to identify the process or set of
processes that is to be affected by this call. This parameter points
to a procset.h structure which defines the selection process. In the
<sys/procset.h>, a setprocset macro is defined that displays a means of
initializing the procset structure. For more information on this
structure, see the procset(4) reference page.
RETURN VALUE
This system call returns the same values as the priocntl function.
ERRORS
This system call returns the same errors as priocntl function.
