QNX SDP8.0C Library ReferenceAPIDeveloper
Return an endian-swapped 64-bit value
Synopsis:
#include <gulliver.h>
uint64_t ENDIAN_RET64( uint64_t num );
Arguments:
- num
- The number you want to convert.
Library:
libc
Use the -l c option to qcc to link against this library. This library is usually included automatically.
Description:
The ENDIAN_RET64() macro returns the endian-swapped value of num.
Returns:
The endian-swapped value of num.
Examples:
Swap the endianness of a value:
#include <stdio.h>
#include <stdlib.h>
#include <gulliver.h>
#include <inttypes.h>
int main( void )
{
uint64_t val = 0x1234deadbeef5678;
printf( "0x%016llx = 0x%016llx\n",
val, ENDIAN_RET64( val ) );
return EXIT_SUCCESS;
}
This prints:
0x1234deadbeef5678 = 0x7856efbeadde3412
