my code requirement is that a string between two macros is to be displayed at the console. Like this:


TRACE << "hello world" << ENDTRACE;


Question is: how should the two MACROS be defined....

I'm not sure how. Consider this code:

{
char str[50];
char *hex_str = "1A2";
int int_output = 0;

Hi,

Is there any library function available which will convert a passed hex string to its equivalent integer value???

Something like atoi() except that the input contains a hexadecimal string...

I checked out Xerces, XML4C and MSXML.

All of these are pretty cumbersome to use. Is there any short-n-sweet parser available which may...

Actually, the compiler allocates space for it. Only, you wouldn't be able to modify the string.

Just like saying:


char *ptr = "Hello World";
printf( "string is: %s\n", ptr );


As pointed...

Regarding the size in recv(), you could put the recv() in while loop till it returns 0 or less. Something like this:



char data_str[OPTIMIZED_INITIAL_SIZE];
int bytes_read = 1;...

Words of wisdom:

I wouldn't write an Operating System in Java, I'd go for C or C++. And I wouldn't implement a WebService in C, I'd most definitely go for Java.

So, what to use or what not to...

Here's an idea:

Try doing a connect() directly to the IP address you are trying to ping. You would have the information you want in just one function call (well, actually two. you'd do a socket()...

Try initializing the recvBuf to 0 before you do a recv() in it:


memset( recvBuf, 0, 256 );

Also, as vVv pointed out, you are recv()ing for max of sizeof(recvBuf) bytes which basically is:...
