### CreateDataSource(self, *args, **kwargs) | source code
    CreateDataSource(self, char utf8_path, char options = None) -> DataSource

    OGRDataSourceH
    OGR_Dr_CreateDataSource(OGRSFDriverH hDriver, const char *pszName,
    char **papszOptions)

    This function attempts to create a new data source based on the passed
    driver.

    The papszOptions argument can be used to control driver specific
    creation options. These options are normally documented in the format
    specific documentation.

    It is important to call OGR_DS_Destroy() when the datasource is no
    longer used to ensure that all data has been properly flushed to disk.

    This function is the same as the C++ method
    OGRSFDriver::CreateDataSource().

    Parameters:
    -----------

    hDriver:  handle to the driver on which data source creation is based.

    pszName:  the name for the new data source. UTF-8 encoded.

    papszOptions:  a StringList of name=value options. Options are driver
    specific, and driver information can be found at the following
    url:http://www.gdal.org/ogr/ogr_formats.html

    NULL is returned on failure, or a new OGRDataSource handle on success.

### CopyDataSource(self, *args, **kwargs) | source code
    CopyDataSource(self, DataSource copy_ds, char utf8_path, char options = None) -> DataSource

    OGRDataSourceH
    OGR_Dr_CopyDataSource(OGRSFDriverH hDriver, OGRDataSourceH hSrcDS,
    const char *pszNewName, char **papszOptions)

    This function creates a new datasource by copying all the layers from
    the source datasource.

    It is important to call OGR_DS_Destroy() when the datasource is no
    longer used to ensure that all data has been properly flushed to disk.

    This function is the same as the C++ method
    OGRSFDriver::CopyDataSource().

    Parameters:
    -----------

    hDriver:  handle to the driver on which data source creation is based.

    hSrcDS:  source datasource

    pszNewName:  the name for the new data source.

    papszOptions:  a StringList of name=value options. Options are driver
    specific, and driver information can be found at the following
    url:http://www.gdal.org/ogr/ogr_formats.html

    NULL is returned on failure, or a new OGRDataSource handle on success.

### Open(self, *args, **kwargs) | source code
    Open(self, char utf8_path, int update = 0) -> DataSource

    OGRDataSourceH OGR_Dr_Open(OGRSFDriverH
    hDriver, const char *pszName, int bUpdate)

    Attempt to open file with this driver.

    This function is the same as the C++ method OGRSFDriver::Open().

    Parameters:
    -----------

    hDriver:  handle to the driver that is used to open file.

    pszName:  the name of the file, or data source to try and open.

    bUpdate:  TRUE if update access is required, otherwise FALSE (the
    default).

    NULL on error or if the pass name is not supported by this driver,
    otherwise an handle to an OGRDataSource. This OGRDataSource should be
    closed by deleting the object when it is no longer needed.

### DeleteDataSource(self, *args) | source code
    DeleteDataSource(self, char utf8_path) -> int

    OGRErr
    OGR_Dr_DeleteDataSource(OGRSFDriverH hDriver, const char
    *pszDataSource)

    Delete a datasource.

    Delete (from the disk, in the database, ...) the named datasource.
    Normally it would be safest if the datasource was not open at the
    time.

    Whether this is a supported operation on this driver case be tested
    using TestCapability() on ODrCDeleteDataSource.

    This method is the same as the C++ method
    OGRSFDriver::DeleteDataSource().

    Parameters:
    -----------

    hDriver:  handle to the driver on which data source deletion is based.

    pszDataSource:  the name of the datasource to delete.

    OGRERR_NONE on success, and OGRERR_UNSUPPORTED_OPERATION if this is
    not supported by this driver.

### TestCapability(self, *args) | source code
    TestCapability(self, char cap) -> bool

    int
    OGR_Dr_TestCapability(OGRSFDriverH hDriver, const char *pszCap)

    Test if capability is available.

    One of the following data source capability names can be passed into
    this function, and a TRUE or FALSE value will be returned indicating
    whether or not the capability is available for this object.

    ODrCCreateDataSource: True if this driver can support creating data
    sources.

    ODrCDeleteDataSource: True if this driver supports deleting data
    sources.

    The #define macro forms of the capability names should be used in
    preference to the strings themselves to avoid mispelling.

    This function is the same as the C++ method
    OGRSFDriver::TestCapability().

    Parameters:
    -----------

    hDriver:  handle to the driver to test the capability against.

    pszCap:  the capability to test.

    TRUE if capability available otherwise FALSE.

### GetName(self) | source code
    const char*
    OGR_Dr_GetName(OGRSFDriverH hDriver)

    Fetch name of driver (file format). This name should be relatively
    short (10-40 characters), and should reflect the underlying file
    format. For instance "ESRI Shapefile".

    This function is the same as the C++ method OGRSFDriver::GetName().

    Parameters:
    -----------

    hDriver:  handle to the the driver to get the name from.

    driver name. This is an internal string and should not be modified or
    freed.
Returns: char
