HP-UX Itanium 64 - C Support for int 32

[abadreamer]

I have an old program written in C, we need to use int32 on it, what is the appropriate type to use? is it "int32" or what?

Whose C? For what?

If I _knew_ what your "int32" was, then I
might be able to suggest a standard type to
use for it. I can _guess_ that it's a 32-bit
signed integer, so I'd guess that "int" would
be suitable.

Invisible code can be hard for us
non-psychics to interpret.

Thanks for reply
I mean written in ANSI-C programming language, i though C was obvious.
i'm compiling on HP Itanium 64bit, and i need to define an integer variable of 32 bit length, can any one help in this, for example in Solaris i use something like
typedef signed int32 TYP_INT32;

thanks for your reply

Then say that. With my weak psychic powers,
I don't know what "int32" means to you.

C may be obvious. What you want is another
question.

Why? What's wrong with plain, old,
ANSI-standard "int"?

dyi # cat siz.c
#include

main()
{
printf( " char = %d, int = %d, long = %d, long long = %d, void* = %d.\n",
sizeof( char), sizeof( int), sizeof( long),
sizeof( long long), sizeof( void *));
}

dyi # cc -o siz siz.c

dyi # ./siz
char = 1, int = 4, long = 4, long long = 8, void* = 4.

Looks to me like 32 bits.

You can just use int. If you want to use int32_t, you can include <inttypes.h>.
