ENDIAN_BE16()

QNX SDP8.0C Library ReferenceAPIDeveloper

Return a big-endian 16-bit value in native format

Synopsis:

#include <gulliver.h>

uint16_t ENDIAN_BE16( uint16_t num );

Arguments:

num
The big-endian 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_BE16() macro returns the native version of the big-endian value num.

Returns:

The native-endian value of num.

Examples:

Convert a big-endian value to native-endian:

#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_BE16( val ) );

    return EXIT_SUCCESS;
}

On a little-endian system, this prints:

0x1234 = 0x3412

Classification:

QNX OS

Safety:
Cancellation pointNo
Signal handlerYes
ThreadYes

Caveats:

ENDIAN_BE16() is implemented as a macro.
