Return a big-endian 32-bit value in native format
#include <gulliver.h>
uint32_t ENDIAN_BE32( uint32_t num );
- num
- The big-endian number you want to convert.

Use the -l c option to

to link against this library.
This library is usually included automatically.
The ENDIAN_BE32() macro returns the native version of the
big-endian value num.
The native-endian value of num.
Convert a big-endian value to native-endian:
#include <stdio.h>
#include <stdlib.h>
#include <gulliver.h>
#include <inttypes.h>
int main( void )
{
uint32_t val = 0xdeadbeef;
printf( "0x%08x = 0x%08x\n",
val, ENDIAN_BE32( val ) );
return EXIT_SUCCESS;
}
On a little-endian system, this prints:
0xdeadbeef = 0xefbeadde
