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

Caveats:
ENDIAN_BE16() is implemented as a macro.
