ENDIAN_RET16()
Return an endian-swapped 16-bit value
Synopsis:
#include <gulliver.h>
uint16_t ENDIAN_RET16( uint16_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_RET16() 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 ) { uint16_t val = 0x1234; printf( "0x%04x = 0x%04x\n", val, ENDIAN_RET16( val ) ); return EXIT_SUCCESS; }
This prints:
0x1234 = 0x3412
