Member Function Documentation

int32 OsclAsyncFile::Close (    )

void OsclAsyncFile::Delete (  OsclAsyncFile *    )  [static]

int32 OsclAsyncFile::EndOfFile (    )

uint32 OsclAsyncFile::Flush (    )  [inline]

OsclAsyncFile* OsclAsyncFile::NewL (  OsclNativeFile &    aAsyncFile, int32    aCacheSize, PVLogger *    )  [static]

Two-phased constructor. Parameters: aAsyncFile:  open handle for async file read. Note: it is the caller's job to open/close this file handle. aSyncFile:  duplicate open handle for sync file read. Note: it is the caller's job to open this file handle, but this class will close the handle. aCacheSize:  size of one of the individual cache buffers. The total cached data size will be larger, since multiple buffers are used. aStartAsyncRead:  When true, async file read will start immediately. When false, read will not begin until StartAsyncRead is called.
