Signal Handling--ref

In the GNU system,SIGLOSTis generated when any server program dies unexpectedly. It is usually fine to ignore the signal; whatever call was made to the server that died just returns an error.

intSIGXCPU

CPU time limit exceeded. This signal is generated when the process exceeds its soft resource limit on CPU time. See section.

intSIGXFSZ

File size limit exceeded. This signal is generated when the process attempts to extend a file so it exceeds the process's soft resource limit on file size. See section.

intSIGUSR1

intSIGUSR2

TheSIGUSR1andSIGUSR2signals are set aside for you to use any way you want. They're useful for simple interprocess communication,if you write a signal handler for them in the program that receives the signal.

There is an example showing the use ofSIGUSR1andSIGUSR2in section.
