我知道,我可以掩盖在手递执行时发出的信号(使用 s子)。 然而,我想知道,在我更新一些全球变量时,如何掩盖一个信号。
此外,我想知道,在某个用户确定的职能执行时如何掩盖一个信号。
这2件事情是可能的吗?
任何帮助都将受到赞赏。

你可以称之为“签字”你想要的任何时候;或者说是为了(a)把信号手写给某些习俗法典,或者(b)通过向全国人民力量联盟提出手脚论点来澄清。
这一联系可能有助于:
有可能用<代码>sigblock(>阻断信号。 当信号被锁定时,将发出信号。
HOWEVER——这是昂贵的。 你们必须进行劝说,阻止和劝说打破僵局。 如果你经常这样做,这可能会非常缓慢。 因此,有一些替代办法:
volatile
flag. In your signal handler, check for this flag; if you see it, write()
to a pipe
the signal number and immediately return. In your signal handler, check back for a signal on this pipe, and re-raise
the signal at that point.For example, let s say I want to find a particular word or number in a file. The contents are in sorted order (obviously). Since I want to run a binary search on the file, it seems like a real waste ...
