| 750 | # Usage: check_signal [ -{signal} | {signal} ] #
|
---|
| 751 | # #
|
---|
| 752 | # Purpose: Check if signal is a program termination signal or a control signal #
|
---|
| 753 | # This is not defined by any LSB draft, however, it is required to #
|
---|
| 754 | # check the signals to determine if they are intended to end a #
|
---|
| 755 | # program or simply to control it. #
|
---|
| 756 | # #
|
---|
| 757 | # Inputs: Accepts a single string value in the form or -{signal} or {signal} #
|
---|
| 758 | # #
|
---|
| 759 | # Return values: #
|
---|
| 760 | # 0 - Signal is used for program termination #
|
---|
| 761 | # 1 - Signal is used for program control #
