ENDIAN_BE32()

Return a big-endian 32-bit value in native format

Synopsis:

#include <gulliver.h>

uint32_t ENDIAN_BE32( uint32_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_BE32() 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 )
{
    uint32_t val = 0xdeadbeef;
    
    printf( "0x%08x = 0x%08x\n",
            val, ENDIAN_BE32( val ) );

    return EXIT_SUCCESS;
}

On a little-endian system, this prints:

0xdeadbeef = 0xefbeadde

Classification:

QNX Neutrino

Safety:
Cancellation point	No
Interrupt handler	Yes
Signal handler	Yes
Thread	Yes

Caveats:

ENDIAN_BE32() is implemented as a macro.
