C++ Polling Class for BSD/MacOS & Linux (in-progress)
It is recommended that you use cmake and link against the "pollster" library rule created by this project. Code:
#include <Pollster.hpp>
//Create subclass of Pollster::Handler
class ExampleHandler : Pollster::Handler {
public:
//Action when new data is available on fd
void operator()(int fd) { /*...*/ }
//Action to perform upon adding fd to Pollster
void connect(int fd) { /*...*/ }
//Action to perform when pollster fails or when fd disconnects
//Should close fd and cleanup and related data
//Note, if disconnect tries to send data to the fd, it should
//handle SIGPIPEs or send with MSG_DONTWAIT in case the fd
//is already closed before data is sent
void disconnect(int fd, std::string reason) { /*...*/ }
};
//Create instance of pollster providing a handler instance and the max clients to poll
ExampleHandler p;
Pollster poll(10, p);
//Add clients
if(!poll.addClient(fd)){
//Handle error or too many clients
} cmake rule:
#build pollster before any dependant executables/libraries
add_subdirectory(Pollster)
#generate executable here
#i.e.
add_executable(test test.cpp) #example
#link against pollster
target_link_libraries(test pollster)
