tracing send and recv system call
Hi, I am tracing send and recv system call .From user space to kernel space switching send in kernel space not going into sys_send .It directly going into sys_sendto . I am using linux 2.6.32.60 for this operation.my printk statement is printed in sys_sendto but not in sys_send. Is it right way of calling.

Apparently glibc implements send() using the sendto() syscall. The problem isn't really with the traces you added to the kernel, but that you forgot there's another layer between your application and the kernel. Regards. Kristof
