Hi,

I am used to the itoa function in Watcom C compiler. Looks like there is
no equivalent in gcc in Linux.

Does any one know a shorter way to do 'itoa' 'ltoa' 'ftoa' etc.

Please Help!

Have you looked at sprintf(3) ???

ie:

char __print_buffer[1024];
#define itoa(num) sprintf(__print_buffer,"%d",num)
#define ltoa(num) sprintf(__print_buffer,"%d",num)
#define ftoa(num) sprintf(__print_buffer,"%f",num)

Although the above should work on linux, it's a good idea to use %ld here.

Witty .sig under construction.

You didn't ask for C++ but let's just look at it:
-------------------
#include <String.h>
#include <stream.h>

int i;
...
String s = dec(i);
-------------------

Why so big?

: #define itoa(num) sprintf(__print_buffer,"%d",num)
: #define ltoa(num) sprintf(__print_buffer,"%d",num)
: #define ftoa(num) sprintf(__print_buffer,"%f",num)

Mark.

sprintf(buffer, "%d", n)

If portability is an issue, you shouldn't rely on the return value
of sprintf. SYSV derivatives return a length instead of the buffer
pointer.
