- Functions
- int BRLAPI_STDCALL brlapi_getDriverName (char *buffer, size_t size)
int BRLAPI_STDCALL brlapi__getDriverName (brlapi_handle_t *handle, char
*buffer, size_t size)
- int BRLAPI_STDCALL brlapi_getDisplaySize (unsigned int *x, unsigned int
*y)
- int BRLAPI_STDCALL brlapi__getDisplaySize (brlapi_handle_t *handle,
unsigned int *x, unsigned int *y)
Detailed Description
Before using Raw mode or key codes, the application should always check
the type of the connected terminal, to be sure it is really the one it
expects.
One should also check for display size, so as to adjust further
displaying on it.
Define Documentation
- #define BRLAPI_MAXNAMELENGTH 31 Maximum name length for names embeded in
- BrlAPI packets, not counting any termination character
Function Documentation
- int BRLAPI_STDCALL brlapi__getDisplaySize (brlapi_handle_t * handle,
- unsigned int * x, unsigned int * y)
- int BRLAPI_STDCALL brlapi__getDriverName (brlapi_handle_t * handle, char *
- buffer, size_t size)
- int BRLAPI_STDCALL brlapi_getDisplaySize (unsigned int * x, unsigned int *
- y) Return the size of the braille display
- int BRLAPI_STDCALL brlapi_getDriverName (char * buffer, size_t size) Return
- the complete name of the driver used by brltty
This function fills its argument with the whole name of the braille
terminal if available, terminated with a '\0'. - Parameters:
buffer is the buffer given by the application;
size is the maximum size for the name buffer. - Returns:
-1 on error, or a positive value giving the size of the needed
buffer, if the supplied one is to small (same as snprintf()).
