sigreturn - return from signal handler and cleanup stack frame |
|
|

!!SYNOPSIS |
|
|
17 |
|
|
|

|
|
|

__int sigreturn(unsigned long__ |
|
|

!!DESCRIPTION |

|

|
|
|
24 |
When the Linux kernel creates the stack frame for a signal |
|
|
25 |
handler, a call to __sigreturn__ is inserted into the |
|
|
26 |
stack frame so that the the signal handler will call |
|
|
27 |
__sigreturn__ upon return. This inserted call to |
|
|
28 |
__sigreturn__ cleans up the stack so that the process can |
|
|
29 |
restart from where it was interrupted by the |
|
|
30 |
signal. |
|
|
31 |
!!RETURN VALUE |
|
|
32 |
|
|
|
33 |
|
|
|
34 |
__sigreturn__ never returns. |
|
|
35 |
!!WARNING |
|
|
36 |
|
|
|
37 |
|
|
|
38 |
The __sigreturn__ call is used by the kernel to implement |
|
|
39 |
signal handlers. It should __never__ be called directly. |
|
|
40 |
Better yet, the specific use of the ''__unused'' argument |
|
|
41 |
varies depending on the architecture. |
|
|
42 |
!!CONFORMING TO |
|
|
43 |
|
|
|
44 |
|
|
|
45 |
__sigreturn__ is specific to Linux and should not be used |
|
|
46 |
in programs intended to be portable. |
