Well, I am not even sure if its failing, cause at the other end I have a select call and it wakes up and reads the data I sent fine.
Ok here is the issue, I have a UDP socket(non blocking) through which I push some data to another port. At the other end I have select loop, waiting for this data.... (6 Replies)

offsetof
OFFSETOF(3) Linux Programmer's Manual OFFSETOF(3)NAME
offsetof - offset of a structure member
SYNOPSIS
#include <stddef.h>
size_t offsetof(type, member);
DESCRIPTION
The macro offsetof() returns the offset of the field member from the start of the structure type.
This macro is useful because the sizes of the fields that compose a structure can vary across implementations, and compilers may insert
different numbers of padding bytes between fields. Consequently, an element's offset is not necessarily given by the sum of the sizes of
the previous elements.
A compiler error will result if member is not aligned to a byte boundary (i.e., it is a bit field).
RETURN VALUE
offsetof() returns the offset of the given member within the given type, in units of bytes.
CONFORMING TO
C89, C99, POSIX.1-2001.
EXAMPLE
On a Linux/i386 system, when compiled using the default gcc(1) options, the program below produces the following output:
$ ./a.out
offsets: i=0; c=4; d=8 a=16
sizeof(struct s)=16
Program source
#include <stddef.h>
#include <stdio.h>
#include <stdlib.h>
int
main(void)
{
struct s {
int i;
char c;
double d;
char a[];
};
/* Output is compiler dependent */
printf("offsets: i=%ld; c=%ld; d=%ld a=%ld
",
(long) offsetof(struct s, i),
(long) offsetof(struct s, c),
(long) offsetof(struct s, d),
(long) offsetof(struct s, a));
printf("sizeof(struct s)=%ld
", (long) sizeof(struct s));
exit(EXIT_SUCCESS);
}
