That's a lot of header work...I wonder how much of that evolved as you tested and found the original tricks didn't work on a particual machine?
For all that...a simple startup application call during runtime may have been worth it. Something like:
Network order is defined as big endian...so if the machine stores differently than the network order then htons will switch up the bytes. This will, of course, result in its returning something other than the input value.
Easy enough if you need the data at runtime...doesn't help you much if you need it at compile time, of course.
Can anybody help me in finding out a solution for the problem below?
When we write .unix or .sh files in windows OS and port them to Unix platforms there is a character ^M inserted at the end of each line of the script file.

htonl
BYTEORDER(3) Linux Programmer's Manual BYTEORDER(3)NAME
htonl, htons, ntohl, ntohs - convert values between host and network byte order
SYNOPSIS
#include <arpa/inet.h>
uint32_t htonl(uint32_t hostlong);
uint16_t htons(uint16_t hostshort);
uint32_t ntohl(uint32_t netlong);
uint16_t ntohs(uint16_t netshort);
DESCRIPTION
The htonl() function converts the unsigned integer hostlong from host byte order to network byte order.
The htons() function converts the unsigned short integer hostshort from host byte order to network byte order.
The ntohl() function converts the unsigned integer netlong from network byte order to host byte order.
The ntohs() function converts the unsigned short integer netshort from network byte order to host byte order.
On the i386 the host byte order is Least Significant Byte first, whereas the network byte order, as used on the Internet, is Most Signifi-
cant Byte first.
CONFORMING TO
POSIX.1-2001.
Some systems require the inclusion of <netinet/in.h> instead of <arpa/inet.h>.
