Gets a handle to an open file

FILE *sm_fio_handle(int file_stream);

file_stream

A handle to the required file stream, obtained by sm_fio_open.

C only

• · FILE * pointer to the specified file.

• · NULL: Failure—for example, the file is closed. Call sm_fio_error to ascertain the nature of the failure.

sm_fio_handle gets a FILE * pointer to a JPL file stream opened by sm_fio_open. You can pass this handle to routines written in C. This function lets you write your own extensions to Panther file I/O functions.

Note: This function cannot be called from JPL.
