ENDIAN_BE64()
QNX SDP8.0C Library ReferenceAPIDeveloper
Return a big-endian 64-bit value in native format
Synopsis:
#include <gulliver.h>
uint64_t ENDIAN_BE64( uint64_t num );
Arguments:
- num
- The big-endian 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_BE64() macro returns the native version of the big-endian value num.
Returns:
The native-endian value of num.
Examples:
Convert a big-endian value to native-endian:
#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_BE64( val ) );
return EXIT_SUCCESS;
}
On a little-endian system, this prints:
0x1234deadbeef5678 = 0x7856efbeadde3412

Caveats:
ENDIAN_BE64() is implemented as a macro.
