\c block prevents events triggered by \c fish or the
|
|
|
|
|
<a href="commands.html#emit"><code>emit</code></a> command from
|
|
|
|
|
being delivered and acted upon while the block is in place.
|
|
|
|
|
|
|
|
|
|
In functions, \c block can be useful while performing work that
|
|
|
|
|
should not be interrupted by the shell.
|
|
|
|
|
|
|
|
|
|
The block can be removed. Any events which triggered while the
|
|
|
|
|
block was in place will then be delivered.
|
|
|
|
|
|
|
|
|
|
Event blocks should not be confused with code blocks, which are created
|
|
|
|
|
with <code>begin</code>, <code>if</code>, <code>while</code> or
|
|
|
|
|
<code>for</code>
|
|
|
|
|
|
|
|
|
|
The following parameters are available:
|
|
|
|
|
|
|
|
|
|
- <tt>-l</tt> or <tt>--local</tt> Release the block automatically at the end of the current innermost code block scope
|
2005-12-15 02:07:44 +08:00
|
|
|
- <tt>-g</tt> or <tt>--global</tt> Never automatically release the lock
|
|
|
|
|
- <tt>-e</tt> or <tt>--erase</tt> Release global block
