ENDIAN_RET32()

Return an endian-swapped 32-bit value

Synopsis:

#include <gulliver.h>

uint32_t ENDIAN_RET32( uint32_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_RET32() 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 )
{
    uint32_t val = 0xdeadbeef;
    
    printf( "0x%08x = 0x%08x\n",
            val, ENDIAN_RET32( val ) );

    return EXIT_SUCCESS;
}

This prints:

0xdeadbeef = 0xefbeadde

Classification:

QNX Neutrino

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

Caveats:

ENDIAN_RET32() is implemented as a macro.
