- Cap_createContext
  
  com.sun.jna.Pointer Cap_createContext()
  
  Initialize the capture library
  
  Returns:
  
  The context ID.
  Original signature : CapContext Cap_createContext()

- Cap_releaseContext
  
  int Cap_releaseContext(com.sun.jna.Pointer ctx)
  
  Un-initialize the capture library context
  
  Parameters:
  
  ctx - The ID of the context to destroy.
  
  Returns:
  
  The context ID.
  Original signature : CapResult Cap_releaseContext(CapContext)
  native declaration : /Users/romanvg/dev/openpnp-capture/include/openpnp-capture.h:85
- Cap_getDeviceCount
  
  int Cap_getDeviceCount(com.sun.jna.Pointer ctx)
  
  Get the number of capture devices on the system.
  note: this can change dynamically due to the
  pluggin and unplugging of USB devices.
  
  Parameters:
  
  ctx - The ID of the context.
  
  Returns:
  
  The number of capture devices found.
  Original signature : uint32_t Cap_getDeviceCount(CapContext)
  native declaration : /Users/romanvg/dev/openpnp-capture/include/openpnp-capture.h:93
- Cap_getDeviceName
  
  com.sun.jna.Pointer Cap_getDeviceName(com.sun.jna.Pointer ctx, int index)
  
  Get the name of a capture device.
  This name is meant to be displayed in GUI applications,
  i.e. its human readable.
  if a device with the given index does not exist,
  NULL is returned.
  
  Parameters:
  
  ctx - The ID of the context.
  
  index - The device index of the capture device.
  
  Returns:
  
  a pointer to an UTF-8 string containting the name of the capture device.
  Original signature : char* Cap_getDeviceName(CapContext, CapDeviceID)
  native declaration : /Users/romanvg/dev/openpnp-capture/include/openpnp-capture.h:105
- Cap_getDeviceUniqueID
  
  com.sun.jna.Pointer Cap_getDeviceUniqueID(com.sun.jna.Pointer ctx, int index)
  
  Get the unique name of a capture device.
  The string contains a unique concatenation
  of the device name and other parameters.
  These parameters are platform dependent.
  Note: when a USB camera does not expose a serial number,
  platforms might have trouble uniquely identifying
  a camera. In such cases, the USB port location can
  be used to add a unique feature to the string.
  This, however, has the down side that the ID of
  the camera changes when the USB port location
  changes. Unfortunately, there isn't much to
  do about this.
  if a device with the given index does not exist,
  NULL is returned.
  
  Parameters:
  
  ctx - The ID of the context.
  
  index - The device index of the capture device.
