Functions

Future< short > process::io::poll (int_fd fd, short events)
 Returns the events (a subset of the events specified) that can be performed on the specified file descriptor without blocking. More...
 
Future< size_t > process::io::read (int_fd fd, void *data, size_t size)
 Performs a single non-blocking read by polling on the specified file descriptor until any data can be be read. More...
 
Future< std::string > process::io::read (int_fd fd)
 Performs a series of asynchronous reads, until EOF is reached. More...
 
Future< size_t > process::io::write (int_fd fd, const void *data, size_t size)
 Performs a single non-blocking write by polling on the specified file descriptor until data can be be written. More...
 
Future< Nothingprocess::io::write (int_fd fd, const std::string &data)
 Performs a series of asynchronous writes, until all of data has been written. More...
 
Future< Nothingprocess::io::redirect (int_fd from, Option< int_fd > to, size_t chunk=4096, const std::vector< lambda::function< void(const std::string &)>> &hooks={})
 Redirect output from the 'from' file descriptor to the 'to' file descriptor (or /dev/null if 'to' is None). More...
