Methods
void seek ( PRInt32 whence , PRInt64 offset )
void setEOF ( )
PRInt64 tell ( )
void seek ( PRInt32 whence , PRInt64 offset )
This method moves the stream offset of the steam implementing this interface.
- Arguments:
- whence: specifies how to interpret the 'offset' parameter in setting the stream offset associated with the implementing stream.
- offset: specifies a value, in bytes, that is used in conjunction with the 'whence' parameter to set the stream offset of the implementing stream. A negative value causes seeking in the reverse direction.
