#include <file.hh>
Public Member Functions | |
void | open (std::string name, bool read, bool write) |
Open a new file in the object. | |
void | close () |
Close the file. | |
![]() | |
void | read_custom (read_custom_t cb) |
Poll for read with a custom callback to poll. More... | |
void | read_priority_custom (read_custom_t cb) |
Poll for priority read with a custom callback to poll. | |
void | read (read_t cb) |
Poll for read and set read callback (resets custom callback) More... | |
void | read_priority (read_t cb) |
Poll for priority read and set read callback (resets custom callback) | |
void | read_lines (read_lines_t cb) |
Poll for read and set read lines callback (resets custom and read callback). Polls for priority read as well. | |
void | unread (bool flush_buffer=false, flush_t cb=flush_t()) |
Stop polling for read (including priority read). | |
void | write (std::string const &data, write_done_t cb=write_done_t()) |
Write data and set a callback (defaults to none). | |
void | write_raw (std::string const &data, write_done_t cb=write_done_t()) |
Write data, ignoring the filter, and set a callback (defaults to none). | |
bool | write_block (relative_time timeout=relative_time(-1, 0)) |
Block until write buffer is empty. More... | |
std::string & | read_block (relative_time timeout=relative_time(-1, 0)) |
Block until data is read, try writing if there is a write buffer. More... | |
std::string | read_line_block (relative_time timeout=relative_time(-1, 0)) |
Call read_block until a line has been read, or the timeout expires. | |
void | set_fd (int fd) |
Change file descriptor. | |
void | in_filter (filter_t cb) |
If set, incoming data is filtered through this callback before it is put into the buffer. | |
void | out_filter (filter_t cb) |
If set, outgoing data is filtered through this callback before it is sent to the file descriptor. | |
void | set_error (error_t cb) |
Set a callback for all error types at once. More... | |
void | set_poll_error (error_t cb) |
Callback for errors from poll. | |
void | set_read_error (error_t cb) |
Callback for errors from read. | |
void | set_write_error (error_t cb) |
Callback for errors from write. | |
void | set_eof (error_t cb) |
Callback for end of file. | |
void | read_reset () |
Stop reading, delete the buffer. | |
void | write_reset () |
Stop writing, delete the buffer. | |
void | reset () |
Stop reading and writing, delete the buffers. | |
int | get_fd () const |
Get the fd. This function should mostly be used by derived classes. | |
Glib::RefPtr< Glib::MainContext > | get_main_context () |
Get the main context. Also mostly used by derived classes. | |
![]() | |
template<typename _T > | |
Glib::RefPtr< _T > | cast_dynamic () |
Identical to GLib::RefPtr <>::cast_dynamic, but nicer to type. | |
Static Public Member Functions | |
static Glib::RefPtr< file > | create (Glib::RefPtr< Glib::MainContext > main=Glib::MainContext::get_default()) |
Create a new file object. | |
![]() | |
static Glib::RefPtr< fd > | create (int value=-1, Glib::RefPtr< Glib::MainContext > main=Glib::MainContext::get_default()) |
Create a new fd. | |
Additional Inherited Members | |
![]() | |
typedef sigc::slot0< void > | read_custom_t |
Function pointer to call when data is read from fd. | |
typedef sigc::slot1< bool, std::string & > | read_t |
Function pointer to call when fd is ready for reading. | |
typedef sigc::slot1< void, std::string const & > | read_lines_t |
Function pointer to call when a complete line has arrived. | |
typedef sigc::slot0< void > | error_t |
Function pointer to call when an error occurs. | |
typedef sigc::slot0< void > | write_done_t |
Function pointer to call when data has been written. | |
typedef sigc::slot1< void, std::string & > | filter_t |
Function pointer to filter in and outgoing data. | |
typedef sigc::slot0< void > | flush_t |
Function pointer to signal that all data is flushed after unread () | |
![]() | |
fd (int value, Glib::RefPtr< Glib::MainContext > main) | |
Constructor. | |
~fd () | |
Destructor. | |
![]() | |
refbase () | |
Constructor, increments reference count. | |
virtual | ~refbase () |
Destructor, decrements reference count and destroys the object if it reaches 0. | |
template<typename T > | |
Glib::RefPtr< T > | refptr_this () |
Get a RefPtr to this, protected because only members should need it. More... | |
Use normal files with the fd class.
