Technical Reference:BCI2000Remote Library: Difference between revisions

Revision as of 18:31, 5 July 2012

The BCI2000Remote Library provides a C interface to the BCI2000Remote C++ class. It may be used to control the BCI2000 Operator module.

Functions specific to the Library

int BCI2000Release( void* )

purpose: Releases a string buffer, or other object allocated by the library. arguments: String pointer, or handle to object allocated by one of the library functions. returns: 1 if successful, 0 otherwise.

void* BCI2000Remote_New( void )

purpose: Creates a new BCI2000Remote object. arguments: None. returns: A handle to the newly created object.

int BCI2000Remote_Delete( void* )

purpose: Deletes a BCI2000Remote object. arguments: Handle to an existing BCI2000Remote object. returns: 1 if successful, 0 otherwise.

BCI2000Remote Member Functions

The following functions are property accessors, and member functions of BCI2000Remote objects. For documentation, see "Programming Reference:BCI2000Remote Class" on the BCI2000 wiki. In the C-style interface, each function takes a handle to an existing BCI2000Remote object as its first argument. Use BCI2000Remote_New() to create such objects. When a function returns a C string, the caller is responsible for releasing that string once it is done with it. This is done by calling BCI2000Release() on the string. Function that return a C string may return NULL to indicate failure.

double BCI2000Remote_GetTimeout( void* )

void BCI2000Remote_SetTimeout( void*, double timeout )

const char* BCI2000Remote_GetOperatorPath( void* )

void BCI2000Remote_SetOperatorPath( void, const char )

int BCI2000Remote_GetWindowVisible( void* )

void BCI2000Remote_SetWindowVisible( void*, int visible )

enum
{
  BCI2000Remote_Invisible = 0,
  BCI2000Remote_Visible = 1,
  BCI2000Remote_NoChange = 2,
};

const char* BCI2000Remote_GetWindowTitle( void* )

void BCI2000Remote_SetWindowTitle( void, const char )

const char* BCI2000Remote_GetTelnetAddress( void* )

void BCI2000Remote_SetTelnetAddress( void, const char )

int BCI2000Remote_GetConnected( void* )

const char* BCI2000Remote_GetResult( void* )

const char* BCI2000Remote_GetSubjectID( void* )

void BCI2000Remote_SetSubjectID( void, const char )

const char* BCI2000Remote_GetSessionID( void* )

void BCI2000Remote_SetSessionID( void, const char )

const char* BCI2000Remote_GetDataDirectory( void* )

void BCI2000Remote_SetDataDirectory( void, const char )

int BCI2000Remote_Connect( void* )

int BCI2000Remote_Disconnect( void* )

int BCI2000Remote_Execute( void, const char )

NB: This function returns the last command's execution status, which is a true integer, with a value of 0 indicating success in most cases. All other int-returning functions return a boolean integer which is 1 on success, and 0 on failure.

int BCI2000Remote_StartupModules( void, const char )

Provide a zero-delimited list of C strings, containing module names with command line arguments in the form

const char* list = "module1 -arg1 -arg2\0module2 -arg1\0module3 -arg1\0\0";
