Experts,
Can any one please explain about a "File Handle" , what it is.
Can we see it, like an inode number.
- Also what is the significance of it in "Stale NFS file handle" error.

NAME
Entering & leaving tty mode -
How to take control of ttys for direct braille display / read.
Macros
#define BRLAPI_TTY_DEFAULT -1
Functions
int BRLAPI_STDCALL brlapi_enterTtyMode (int tty, const char *driver)
int BRLAPI_STDCALL brlapi__enterTtyMode (brlapi_handle_t *handle, int tty, const char *driver)
int BRLAPI_STDCALL brlapi_enterTtyModeWithPath (int *ttys, int count, const char *driver)
int BRLAPI_STDCALL brlapi__enterTtyModeWithPath (brlapi_handle_t *handle, int *ttys, int count, const char *driver)
int BRLAPI_STDCALL brlapi_leaveTtyMode (void)
int BRLAPI_STDCALL brlapi__leaveTtyMode (brlapi_handle_t *handle)
int BRLAPI_STDCALL brlapi_setFocus (int tty)
int BRLAPI_STDCALL brlapi__setFocus (brlapi_handle_t *handle, int tty)
Detailed Description
Before being able to write on the braille display, the application must tell the server which tty it will handle.
The application must also specify how braille keys will be delivered to it. Two ways are possible: key codes and commands:
o key codes are specific to each braille driver, since the raw key code, as defined in the driver will be given for each key press. Using
them leads to building highly driver-dependent applications, which can yet sometimes be useful to mimic existing proprietary applications
for instance.
o commands means that applications will get exactly the same values as brltty. This allows driver-independent clients, which will hopefully
be nice to use with a lot of different terminals.

brlapi_readKey()
Macro Definition Documentation
#define BRLAPI_TTY_DEFAULT -1
Select the default tty.
The library takes the following steps:
1. Try to get the tty number from the WINDOWID environment variable (for the xterm case).
2. Try to get the tty number from the CONTROLVT environment variable.
3. Read /proc/self/stat (on Linux).

brlapi_enterTtyMode()
Function Documentation
int BRLAPI_STDCALL brlapi__enterTtyMode (brlapi_handle_t *handle, inttty, const char *driver)
int BRLAPI_STDCALL brlapi__enterTtyModeWithPath (brlapi_handle_t *handle, int *ttys, intcount, const char *driver)
int BRLAPI_STDCALL brlapi__leaveTtyMode (brlapi_handle_t *handle)
int BRLAPI_STDCALL brlapi__setFocus (brlapi_handle_t *handle, inttty)
int BRLAPI_STDCALL brlapi_enterTtyMode (inttty, const char *driver)
Ask for some tty, with some key mechanism
Parameters:
tty
o If tty>=0 then take control of the specified tty.
o If tty==BRLAPI_TTY_DEFAULT then take control of the default tty.
driver tells how the application wants brlapi_readKey() to return key presses. NULL or '' means BRLTTY commands are required, whereas a
driver name means that raw key codes returned by this driver are expected.
WINDOWPATH and WINDOWID should be propagated when running remote applications via ssh, for instance, along with BRLAPI_HOST and the
authorization key (see SendEnv in ssh_config(5) and AcceptEnv in sshd_config(5))
Returns:
the used tty number on success, -1 on error
See Also:
brlapi_leaveTtyMode() brlapi_readKey()
int BRLAPI_STDCALL brlapi_enterTtyModeWithPath (int *ttys, intcount, const char *driver)
Ask for some tty specified by its path in the tty tree, with some key mechanism
Parameters:
ttys points on the array of ttys representing the tty path to be got. Can be NULL if nttys is 0.
count gives the number of elements in ttys.
driver has the same meaning as in brlapi_enterTtyMode()
Providing nttys == 0 means to get the root.
See Also:
brlapi_enterTtyMode()
int BRLAPI_STDCALL brlapi_leaveTtyMode (void)
Stop controlling the tty
Returns:
0 on success, -1 on error.
See Also:
brlapi_enterTtyMode()
int BRLAPI_STDCALL brlapi_setFocus (inttty)
Tell the current tty to brltty
This is intended for focus tellers, such as brltty, xbrlapi, screen, ... brlapi_enterTtyMode() must have been called beforehand to tell
where this focus applies in the tty tree.
Returns:
0 on success, -1 on error.
