Effective Endian conversion in x86

Instead of Using the bit shift operators, we can use the assembly instruction bswap provided by x86 systems.
I am using the EAX Register for manipulation because it is the same register used for returning value. So i dont need any extra instruction to move my variable to EAX register

	// Using the X86 instruction bswap and gcc inline assembly
	inline unsigned int ntohl(unsigned int x)
	{
	asm("bswapl %1" : "=a" (x) : "a"(x));
	}
	inline unsigned int htonl(unsigned int x)
	{
	asm("bswapl %1" : "=a" (x) : "a"(x));
	}
