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.

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'.

bufferis the buffer given by the application;
sizeis the maximum size for the name buffer.
-1 on error, or a positive value giving the size of the needed buffer, if the supplied one is to small (same as snprintf()).
