bfsClose()

PROTOTYPE

#include <bfs.h>

int bfsClose(void);

DESCRIPTION

bfsClose() closes the currently open file. If opened in write mode, any buffered output is written to the file before its metadata is written. After bfsClose() returns, a newly created file is persistent: it will exist with valid contents at the next start up.

If successful, bfsClose() returns 0. Otherwise, it sets errno and returns -1.

ERROR CODES

EINVAL	No file is open.
other	An I/O error occurred while writing buffered data or deleting the previous copy of a file opened in update mode.

EXAMPLE

/* Close file and check if successful.                           */
/*---------------------------------------------------------------*/

  perror("error trying to close file!");
