Arguments:

A pointer to 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_SWAP16() macro endian-swaps the value pointed to by num in place.

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;
    ENDIAN_SWAP16( &val );
    
    printf( "val = 0x%04x\n", val );

    return EXIT_SUCCESS;
}

This prints:

val = 0x3412

Classification:

QNX OS

Caveats:

ENDIAN_SWAP16() is implemented as a macro.
