atomic_bits(3C)atomic_bits(3C)NAME
atomic_bits, atomic_set_long_excl, atomic_clear_long_excl - atomic set and clear bit operations
SYNOPSIS
#include <atomic.h>
int atomic_set_long_excl(volatile ulong_t *target, uint_t bit);
int atomic_clear_long_excl(volatile ulong_t *target, uint_t bit);
The atomic_set_long_excl() and atomic_clear_long_excl() functions perform an exclusive atomic bit set or clear operation on target. The
value of bit specifies the number of the bit to be modified within target. Bits are numbered from zero to one less than the maximum number
of bits in a long. If the value of bit falls outside of this range, the result of the operation is undefined.
The atomic_set_long_excl() and atomic_clear_long_excl() functions return 0 if bit was successfully set or cleared. They return -1 if bit
was already set or cleared.
No errors are defined.

SYNOPSIS
#include <atomic.h>
uint8_t atomic_swap_8(volatile uint8_t *target, uint8_t newval);
uchar_t atomic_swap_uchar(volatile uchar_t *target, uchar_t newval);

uint64_t atomic_swap_64(volatile uint64_t *target, uint64_t newval);
void *atomic_swap_ptr(volatile void *target, void *newval);
DESCRIPTION
These functions enable a swap operation to occur atomically. The value stored in target is replaced with newval. The old value is returned
by the function.
RETURN VALUES
These functions return the old of *target.
ERRORS
No errors are defined.

i am using sunOS 5.8. What is the command to know the OS bit (8,32,64...) while the server is under production and is it possible to change from one bit to another??
replies appreciated

I've been trying to compile an application that works on AIX 5L in 32 bit mode on an AIX 5L 64 bit mode machine. In doing so I get a lot of undefined symbol errors.

I had previous implemented the following in my menu.lst to be able to get to 32-bit operations.

Hi guys,
as per subject i am setting up NMON for the above OS but it is 64-bit Linux.
I downloaded the 32-bit NMON for RHEL45 as it is the only one available for RHEL45.
However, I ran into problem with the binary file.

I have a 32bit number and without using for loop,I want to set mbit to n bit.
Say m bit may be 2nd or 5th or 9th or 10th.n bit may be 22nd or 27or 11th bit.
I assume m<n.
Please help me.Thanks
