#define AST_IO_ERR POLLERR |
int ast_hide_password | ( | int | fd | ) |
Set fd into non-echoing mode (if fd is a tty)
int* ast_io_add | ( | struct io_context * | ioc, | |
int | fd, | |||
ast_io_cb | callback, | |||
short | events, | |||
void * | data | |||
) |
ioc | which context to use | |
fd | which fd to monitor | |
callback | callback function to run | |
events | event mask of events to wait for | |
data | data to pass to the callback Watch for any of revents activites on fd, calling callback with data as callback data. Returns a pointer to ID of the IO event, or NULL on failure. |
int* ast_io_change | ( | struct io_context * | ioc, | |
int * | id, | |||
int | fd, | |||
ast_io_cb | callback, | |||
short | events, | |||
void * | data | |||
) |
ioc | which context to use | |
id | ||
fd | the fd you wish it to contain now | |
callback | new callback function | |
events | event mask to wait for | |
data | data to pass to the callback function Change an i/o handler, updating fd if > -1, callback if non-null, and revents if >-1, and data if non-null. Returns a pointero to the ID of the IO event, or NULL on failure. |
void ast_io_dump | ( | struct io_context * | ioc | ) |
Dumps the IO array
int ast_io_remove | ( | struct io_context * | ioc, | |
int * | id | |||
) |
ioc | which io_context to remove it from | |
id | which ID to remove Remove an I/O id from consideration Returns 0 on success or -1 on failure. |
int ast_io_wait | ( | struct io_context * | ioc, | |
int | howlong | |||
) |
ioc | which context to act upon | |
howlong | how many milliseconds to wait Wait for I/O to happen, returning after howlong milliseconds, and after processing any necessary I/O. Returns the number of I/O events which took place. |
int ast_restore_tty | ( | int | fd, | |
int | oldstatus | |||
) |
Restores TTY mode
struct io_context* io_context_create | ( | void | ) |
Create a context for I/O operations Basically mallocs an IO structure and sets up some default values. Returns an allocated io_context structure
void io_context_destroy | ( | struct io_context * | ioc | ) |
Destroys a context
