Use "unsigned int" for 32bit storage in LP32 and LP64. On Jun 1, 2010, at 2:47 PM, Arnab Ganguly wrote:
Dear All,
I am having two below functions.
void for16(unsigned char *&walker, uint16 &value) { uint16 result;
result = ((uint16) *walker++) << 0; result |= ((uint16) *walker++) << 8;
value = result; }
Here uint16 is unsigned short.
void for32(unsigned char *&walker, uint32 &value) { uint32 result;
result = ((uint32) *walker++) << 0; result |= ((uint32) *walker++) << 8; result |= ((uint32) *walker++) << 16; result |= ((uint32) *walker++) << 24;
value = result; }
Here uint32 is unsigned long.
I am not getting same resultant value in case of 32bit and 64bit.How can I make the above code return same result irrespective of 32bit or 64bit machine.I am not clear about the code logic also.Please help me understanding the same. Thanks in advance. -R
