Return an endian-swapped 32-bit value
#include <gulliver.h> uint32_t ENDIAN_RET32( uint32_t num );
libc
Use the -l c option to qcc to link against this library. This library is usually included automatically.
The ENDIAN_RET32() macro returns the endian-swapped value of num.
The endian-swapped value of num.
Swap the endianness of a value:
#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_RET32( val ) );
return EXIT_SUCCESS;
}
This prints:
0xdeadbeef = 0xefbeadde

ENDIAN_RET32() is implemented as a macro.
