Return a big-endian 16-bit value in native format
#include <gulliver.h> uint16_t ENDIAN_BE16( uint16_t num );
libc
Use the -l c option to qcc to link against this library. This library is usually included automatically.
The ENDIAN_BE16() macro returns the native version of the big-endian value num.
The native-endian value of num.
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

ENDIAN_BE16() is implemented as a macro.
