The concept of "current process" doesn't exist inside the kernel. What you're asking doesn't make a ton of sense.

Please couls somebody tell me how to display Configurable Kernel parameters from the command line. I am able to do it from SAM,but would like to dump the command line output to a text file so I can email it off to HP.

Hi All,
Is there a max number of slabs that can be used per kernel module? I'm having a tough time finding out that kind of information, but the array 'node_zonelists' (mmzone.h) has a size of 5. I just want to avoid buffer overruns and other bad stuff.
Cheers,

sched_setparam
SCHED_SETPARAM(2) Linux Programmer's Manual SCHED_SETPARAM(2)
NAME
sched_setparam, sched_getparam - set and get scheduling parameters
SYNOPSIS
#include <sched.h>
int sched_setparam(pid_t pid, const struct sched_param *param);
int sched_getparam(pid_t pid, struct sched_param *param);
struct sched_param {
...
int sched_priority;
...
};
DESCRIPTION
sched_setparam() sets the scheduling parameters associated with the scheduling policy for the process identified by pid. If pid is zero,
then the parameters of the calling process are set. The interpretation of the argument param depends on the scheduling policy of the
process identified by pid. See sched_setscheduler(2) for a description of the scheduling policies supported under Linux.
sched_getparam() retrieves the scheduling parameters for the process identified by pid. If pid is zero, then the parameters of the calling
process are retrieved.
sched_setparam() checks the validity of param for the scheduling policy of the process. The value param->sched_priority must lie within
the range given by sched_get_priority_min(2) and sched_get_priority_max(2).
For a discussion of the privileges and resource limits related to scheduling priority and policy, see sched_setscheduler(2).
POSIX systems on which sched_setparam() and sched_getparam() are available define _POSIX_PRIORITY_SCHEDULING in <unistd.h>.
RETURN VALUE
On success, sched_setparam() and sched_getparam() return 0. On error, -1 is returned, and errno is set appropriately.
ERRORS
EINVAL The argument param does not make sense for the current scheduling policy.
EPERM The calling process does not have appropriate privileges (Linux: does not have the CAP_SYS_NICE capability).
ESRCH The process whose ID is pid could not be found.
CONFORMING TO
POSIX.1-2001.
