Function Documentation

__xbrd_Open (  xbrdHandle  gx, unsigned int  physAddr )  [static]

maps the physical address to an instance of the driver object Parameters: gx  xbrd driver handle previously allocated physAddr  the physical address of the comm IO board Returns: OK for success See also: gClose() Attempts to map physAddr into a local (logical) address. If successful it binds the physical and logical address to the driver object refered to by handle. If unsucessful it clears both the physical and local address for handle and returns ERROR.

Here is the call graph for this function:

int xbrd_Close (  xbrdHandle  gx  )

shuts down the device attached to handle Parameters: gx  xbrd device handle Returns: OK if close successful See also: gOpen()

int xbrd_GetDriverInfo (  DriverInfo *  di  )

fills in driver info struct Parameters: di  pointer to storage to hold driver info Returns: G_OK on successs

int xbrd_GetLogicalAddr (  xbrdHandle  gx, unsigned int *  addr )

returns the logical address attached to handle Parameters: gx  xbrd device handle addr  pointer to storage for holding logical address Returns: G_OK on successs See also: gOpen()

int xbrd_GetPhysAddr (  xbrdHandle  gx, unsigned int *  addr )

returns the physical address attached to handle Parameters: gx  xbrd device handle addr  pointer to storage for holding physical address Returns: G_OK on successs See also: gOpen()

int xbrd_Init (  xbrdHandle  gx  )

Initializes transition board hardware. Parameters: gx  xbrd handle Returns: G_OK on success See source code for laundry list of initiailizations.

Here is the call graph for this function:

xbrd_Open (  xbrdHandle  gx, unsigned int  physAddr )

Initializes a xbrd handle. Parameters: gx  xbrd handle previously allocated physAddr  physical address of transition board Returns: OK for success See also: xbrd_Close()

Here is the call graph for this function:

int xbrd_PrintDriverInfo (  xbrdHandle  gx  )

prints XBRD driver info to stdout Parameters: gx  xbrd device handle Returns: G_OK on successs

Here is the call graph for this function:

unsigned int xbrd_SizeOf (  void   )

Hides the private implemenation of the xbrd registers. Allows user to allocate memory. Returns: the size of struct _xbrd See also: xbrd_Open()
