Hi,=0A =0AI am trying to understand how the kernel invokes the signal handler for = a process, to deliver an asynchronous signal posted by another process.=0A =0AI was looking at the sendsig() function which saves the current user con= text. My question is, when and how does the transition from the kernel mode= to the user mode take place so that the signal handler is invoked?=A0=0A =0A =0AThanks,=0A-shrivatsan=A0=0A=0A=0A
