ENDIAN_RET16()

Return an endian-swapped 16-bit value

Synopsis:

#include <gulliver.h>

uint16_t ENDIAN_RET16( uint16_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_RET16() 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 )
{
    uint16_t val = 0x1234;
    
    printf( "0x%04x = 0x%04x\n",
            val, ENDIAN_RET16( val ) );

    return EXIT_SUCCESS;
}

This prints:

0x1234 = 0x3412

Classification:

Caveats:

ENDIAN_RET16() is implemented as a macro.
