Methods

close

signature(con="FileInputStream"): Flushes any buffers and closes the underlying file. Returns false if an error occurs during the process; use GetErrno to examine the error

GetErrno

signature(object="FileInputStream"): If an I/O error has occurred on this file descriptor, this is the errno from that error. Otherwise, this is zero. Once an error occurs, the stream is broken and all subsequent operations will fail.

SetCloseOnDelete

signature(object="FileInputStream"): set the close on delete behavior.

See ZeroCopyInputStream for inherited methods
