Functions | |
char * | socket_path_from_x11 () |
Try to get the socket path from X11 and return NULL if it doesn’t work. | |

void * | scalloc (size_t size) |
Safe-wrapper around calloc which exits if malloc returns NULL (meaning that there is no more memory available) | |
void * | srealloc (void *ptr, size_t size) |

int | ipc_connect (const char *socket_path) |
Connects to the i3 IPC socket and returns the file descriptor for the socket. | |
int | ipc_send_message (int sockfd, uint32_t message_size, uint32_t message_type, const uint8_t *payload) |
Formats a message (payload) of the given size and type and sends it to i3 via the given socket file descriptor. | |
int | ipc_recv_message (int sockfd, uint32_t message_type, uint32_t *reply_length, uint8_t **reply) |
Reads a message from the given socket file descriptor and stores its length (reply_length) as well as a pointer to its contents (reply). | |
void | fake_configure_notify (xcb_connection_t *conn, xcb_rectangle_t r, xcb_window_t window, int border_width) |
Generates a configure_notify event and sends it to the given window Applications need this to think they’ve configured themselves correctly. | |
uint32_t | get_colorpixel (const char *hex) __attribute__((const )) |
Returns the colorpixel to use for the given hex color (think of HTML). | |
uint32_t | aio_get_mod_mask_for (uint32_t keysym, xcb_key_symbols_t *symbols) |
All-in-one function which returns the modifier mask (XCB_MOD_MASK_*) for the given keysymbol, for example for XCB_NUM_LOCK (usually configured to mod2). | |

Returns the modifier mask (XCB_MOD_MASK_*) for the given keysymbol, for example for XCB_NUM_LOCK (usually configured to mod2). | |
i3Font | load_font (const char *pattern, bool fallback) |

uint32_t aio_get_mod_mask_for | ( | uint32_t | keysym, |
xcb_key_symbols_t * | symbols | ||
) |
All-in-one function which returns the modifier mask (XCB_MOD_MASK_*) for the given keysymbol, for example for XCB_NUM_LOCK (usually configured to mod2).
This function initiates one round-trip. Use get_mod_mask_for() directly if you already have the modifier mapping and key symbols.

void fake_configure_notify | ( | xcb_connection_t * | conn, |
xcb_rectangle_t | r, | ||
xcb_window_t | window, | ||
int | border_width | ||
) |
Generates a configure_notify event and sends it to the given window Applications need this to think they’ve configured themselves correctly.
The truth is, however, that we will manage them.
Referenced by fake_absolute_configure_notify().
uint32_t get_colorpixel | ( | const char * | hex | ) | const |
Returns the colorpixel to use for the given hex color (think of HTML).
Only works for true-color (vast majority of cases) at the moment, avoiding a roundtrip to X11.
The hex_color has to start with #, for example #FF00FF.
NOTE that get_colorpixel() does NOT check the given color code for validity. This has to be done by the caller.
NOTE that this function may in the future rely on a global xcb_connection_t variable called 'conn' to be present.

uint32_t get_mod_mask_for | ( | uint32_t | keysym, |
xcb_key_symbols_t * | symbols, | ||
xcb_get_modifier_mapping_reply_t * | modmap_reply | ||
) |
Returns the modifier mask (XCB_MOD_MASK_*) for the given keysymbol, for example for XCB_NUM_LOCK (usually configured to mod2).
This function does not initiate any round-trips.
int ipc_connect | ( | const char * | socket_path | ) |
Connects to the i3 IPC socket and returns the file descriptor for the socket.
die()s if anything goes wrong.
int ipc_recv_message | ( | int | sockfd, |
uint32_t | message_type, | ||
uint32_t * | reply_length, | ||
uint8_t ** | reply | ||
) |
Reads a message from the given socket file descriptor and stores its length (reply_length) as well as a pointer to its contents (reply).
Returns -1 when read() fails, errno will remain. Returns -2 when the IPC protocol is violated (invalid magic, unexpected message type, EOF instead of a message). Additionally, the error will be printed to stderr. Returns 0 on success.

int ipc_send_message | ( | int | sockfd, |
uint32_t | message_size, | ||
uint32_t | message_type, | ||
const uint8_t * | payload | ||
) |
Formats a message (payload) of the given size and type and sends it to i3 via the given socket file descriptor.
Returns -1 when write() fails, errno will remain. Returns 0 on success.
Referenced by IPC_HANDLER(), ipc_send_event(), and main().
Loads a font for usage, also getting its height.
If fallback is true, the fonts 'fixed' or '-misc-*' will be loaded instead of exiting.
