regarding signals...

[pradeep reddy punnam]

Hi,
 
i am modifing my ../netinet/ip_input.c code so that kernel can inform a 
user process about the arrival of a packet, i want to use signaling 
mechanism for this , i know the pid of the process to which the signal 
should be send, i am looking for exact function that can help me in 
sending SIGIO to procss...
i tryed to use the kill and psignal functions but the system going  
panic when the packet arrives...may be my use of the fuctions is wrong...
can i call a system call from the kernel....
somebody tell me what functions are suitable to call for such a 
situation....
thanking you...
