I am not very sure how to create user defined signal what U have asked.But
looking at the purpose what U are trying I would suggest you to use semaphores,
if it is in kernel space , U can use kernel semaphores in a much easier way.

1.How do i create an user defined signal in Unix/Linux?
Already 2 Signal are allocated for the user defined
operation. Read man 7 signal. SIGUSR1 and 2
2. After Creation of user defined signal (Assume Ctrl + A)
Ctrl + A is NOT a signal. But you can genate a signal
whereever Ctrl+A Pressed.
Assume There are 2 processes running Process A and Process
B. Now this user defined signal (Ctrl + A) should be
triggered automatically (by some mechanism. example
completion of a loop) so once this signal gets triggered.
This signal should be redirected to Process B.
kill( pidOfB, SIGUSR1 )
