Return an endian-swapped 64-bit value
#include <gulliver.h> uint64_t ENDIAN_RET64( uint64_t num );
libc
Use the -l c option to qcc to link against this library. This library is usually included automatically.
The ENDIAN_RET64() macro returns the endian-swapped value of num.
The endian-swapped value of num.
Swap the endianness of a value:
#include <stdio.h> #include <stdlib.h> #include <gulliver.h> #include <inttypes.h> int main( void ) { uint64_t val = 0x1234deadbeef5678; printf( "0x%016llx = 0x%016llx\n", val, ENDIAN_RET64( val ) ); return EXIT_SUCCESS; }
This prints:
0x1234deadbeef5678 = 0x7856efbeadde3412
