Return an endian-swapped 16-bit value
#include <gulliver.h>
uint16_t ENDIAN_RET16( uint16_t num );
- num
- The number you want to convert.
libc
Use the -l c option to
qcc
to link against this library.
This library is usually included automatically.
The ENDIAN_RET16() 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 )
{
uint16_t val = 0x1234;
printf( "0x%04x = 0x%04x\n",
val, ENDIAN_RET16( val ) );
return EXIT_SUCCESS;
}
This prints:
0x1234 = 0x3412
