config SIG_TTIN

|
||||
default 21
|
||||
---help---
|
||||
A process cannot read from the user’s terminal while it is running as a
|
||||
background job. When any process in a background job tries to read from
|
||||
the terminal, all of the processes in the job are sent a SIGTTIN signal.
|
||||
The default action for this signal is to stop the process. For more
|

information about how this interacts with the terminal driver, see Access

to the Controlling Terminal.

config SIG_TTOU

default 22
|
||||
---help---
|
||||
Similar to SIGTTIN, the signal generated by the interrupt driver when a
|
||||
background job wants to read data from the user terminal. The signal does
|
||||
not occur and a read error occurs when the process reading the data blocks
|
||||
or ignores the signal, or when the process group in which the data is being
|
||||
read is an isolated process group. errno is set to ETO. The only difference
|
||||
is that the process can choose to write in the background.

---help---
|

Virtual clock signal. Similar to SIGALRM, but calculates the CPU time
|
