[long description]

Parameters

fd	The file descriptor
offset	The offset from the origin
origin	Position used as a reference for the offset SEEK_SET: beginning of the file SEEK_CUR: current position indicator SEEK_END: end of the file

Returns

MSG_OK if successful, otherwise MSG_TASK_CANCELED

fileMove()

int simgrid::surf::HostImpl::fileMove ( surf_file_t  fd, const char *  fullpath  )

virtual
