HPUX and Compaq problem-urgent
Hi All
Following is the lines of code which simply makes a structure of 1 bit member and 7 bit is unused.Then the structure is initialised with char pointer.The output on HPUX(BIG Endian) and Compaq(Little Endian) are different.On HPUX it gives zero and Compaq it gives 1. I never thought that the bit reading/writing within a byte will be different.Can U help me in understanding this behaviour.
I am looking at Endian issue on two platforms.
#include <stdio.h>
main(){
struct single_t{
unsigned int sh:1;
unsigned int unused:7;
};
struct single_t single,*ptr;
char ch=(char)1;
printf("%d",ch);
ptr=(struct single_t *)&ch;
printf("\nValue from C is %d",ptr->sh);
}

NAME
atomic_dec, atomic_dec_32, atomic_dec_uint, atomic_dec_ulong, atomic_dec_ptr, atomic_dec_64, atomic_dec_32_nv, atomic_dec_uint_nv,
atomic_dec_ulong_nv, atomic_dec_ptr_nv, atomic_dec_64_nv -- atomic decrement operations
SYNOPSIS
#include <sys/atomic.h>
void
atomic_dec_32(volatile uint32_t *ptr);
void
atomic_dec_uint(volatile unsigned int *ptr);
void
atomic_dec_ulong(volatile unsigned long *ptr);
void
atomic_dec_ptr(volatile void *ptr);
void
atomic_dec_64(volatile uint64_t *ptr);
uint32_t
atomic_dec_32_nv(volatile uint32_t *ptr);
unsigned int
atomic_dec_uint_nv(volatile unsigned int *ptr);
unsigned long
atomic_dec_ulong_nv(volatile unsigned long *ptr);
void *
atomic_dec_ptr_nv(volatile void *ptr);
uint64_t
atomic_dec_64_nv(volatile uint64_t *ptr);
DESCRIPTION
The atomic_dec family of functions decrement (by one) the variable referenced by ptr in an atomic fashion.
The *_nv() variants of these functions return the new value.
The 64-bit variants of these functions are available only on platforms that can support atomic 64-bit memory access. Applications can check
for the availability of 64-bit atomic memory operations by testing if the pre-processor macro __HAVE_ATOMIC64_OPS is defined.
SEE ALSO
atomic_ops(3)
HISTORY
The atomic_dec functions first appeared in NetBSD 5.0.
