This is the example from section 4.2, page 71 of K&R2:

double atof( char s[] )
{
int i, sign;
double val, power;

for( i = 0; isspace( s[i] ); ++i )
{
/* skipe the leading whitespace */
}

sign = ( (s[i] == '-') ? -1 : 1 );

if( s[i] == '+'|| s[i] == '-' )
{
++i;
/* skip the leading sign, of any */
}

for( val = 0.0; isdigit( s[i] ); ++i )
{
val = (10.0 * val) + (s[i] - '0');

I know my question is not appropriate for this newgroup. But I only
need right reference to Books on Multithreading and Socket
Programming.

I am more interested in PSOIX threads and socket programming. Please
suggest some good books.

In string.h, I saw

__BEGIN_DECLS

...

__END_DECLS

What's the use of these labels? And why did they always put two
underscores before a name?

I also saw a function prototype declaration:

strlen(const char *) __pure;

Why adding __pure?

Errata for K&R2 page 232 (from
http://www-db-out.research.bell-labs.com/cm/cs/cbook/2ediffs.html):\

232(§A12.5): The result of the defined operator is not replaced
literally by 0L or 1L, nor are undefined names literally by 0L, but just
by plain 0 or 1. However, the constant expression is nevertheless
evaluated as if these and *other constants* appearing have long or
unsigned long type.

When it mentions "these and other constants", what are the other
constants implied?

I mainly keep my code as standard as possible, but I need to branch
out just a tad.

Firstly, if you're writing console programs for a system that has a
screen, a keyboard, and a commandline, then is there any commonly used
library for doing things like clearing the screen, or taking a single
key press from the user?

Secondly, is it OK, do you think, to flout C's rule of having to
define all objects at the beginning of a block? I've seen that a hell
of a lot of C compilers allow you to define objects wherever you want,
and I think it leads to far neater code, especially when it comes to
being able to use const in places where you previously weren't able.

and, Is it possible to call one main function from another main
function?

Thanks guys.

Hello,

a while ago, someone asked a question about software engineering in C,
and someone else proposed Software tools in Pascal of Kernighan. And
pointed that it was not about Pascal at all. I went to Amazon, and the
comments also say the same thing.

Well I just got my order of the book; it came into my mail box today,
and the preface suggests a "Standard Pascal compiler." Oh no! Pascal
doesn't even exist nowadays...

What's in this book that a C programmer can learn? How is it related
to C.
Now that I have it, I must do something with it...

Thanks

Hi

i have used some debug macro and called several times(hundreds) in
the code.

The purpose of the macro was to print the values at that time to the
screen

Now that i have finished debugging, i do not want to execute the
macro.

If i use

#define DEBUG1

the code executes the statements inside the debug except that it is
not printing on the screen, which takes time.

Is there any better way(than commenting all hundreds of lines of
code)?

Thanks in Advance,
VIVEK

some of the syntax wasn't overloaded so much...

Was just musing that if pointer de-referencing and pointer-to-type had
seperate syntax (ie use a character other than '*' for one of them) it would
make things much easier to read. You wouldn't get stuff like:

pthread_create(&thread, NULL, (void *(*)(void*))ThreadProc, (void
*)parameter);
