I am using the UNIX alarm system call to deliver a signal to the current开发者_C百科ly running process on a schedule.
#include <stdio.h> #include <signal.h> static volatile sig_atomic_t being_debugged = 1; static void int3_handler(int signo) { being_debugged = 0; }
I\'m working on some C++ code that uses libsigc++ for signaling (eventing.) I\'m quite new to C++, and I tend to think in C#.The equivalent code to what I want in C# would be something like:
Would like to determine via code whether the voice chan开发者_运维技巧nel on an Android is experiencing noise.
I wrote a Linux program based on a buggy open source library. This library sometimes triggers segfaults that I cannot control. And of course once the library has segfaults, the entire program dies. Ho
i have a question about signals and how they being handled when there is a sql command running. Particularly, i have a python script that runs as a process and inside it anotherprocess is being create
I was told the only/best way to do this is to store the variables in a struct and pass the struct, however it\'s turned into a gpointer and I can\'t seem to be able to turn it back into a struct to re
I did something wrong in my code, where an other process send a SIGUSR2 signal to it: sigset_t sigset;
I came across the following in a vxworks manual and was wondering why this is the case. What types of things do signals do that make them undesirable?
Is int puts(const char*); re-entrant? Can I saf开发者_运维百科ely put it into a signal handler?Here is a table with all functions considered safe for signal handling:
