Detailed Description

fpbase provides the basic operations common to all object file stream I/O.

Definition at line 959 of file tobjstrm.h.

Constructor & Destructor Documentation

fpbase::fpbase ( )

Creates a buffered fpbase object.

fpbase::fpbase ( const char * name, int omode, int prot = filebuf::openprot )

Creates a buffered fpbase object. You can open a file and attach it to the stream by specifying the `name', `omode', and `prot' (protection) arguments.

fpbase::fpbase ( int f )

Creates a buffered fpbase object. You can open a file and attach it to the stream by specifying the file descriptor, `f'.

fpbase::fpbase ( int f, char * b, int len )

Creates a buffered fpbase object. You can set the size and initial contents of the buffer with the `len' and `b' arguments. You can open a file and attach it to the stream by specifying the file descriptor, `f'.

fpbase::~fpbase ( )

Destroys the fpbase object.

Member Function Documentation

void fpbase::attach ( int f )

Attaches the file with descriptor `f' to this stream if possible.

void fpbase::close ( )

Closes the stream and associated file.

void fpbase::open ( const char * name, int omode, int prot = filebuf::openprot )

Opens the named file in the given mode (app, ate, in, out, binary, trunc, nocreate, noreplace) and protection. The opened file is attached to this stream. Reimplemented in ifpstream, ofpstream, and fpstream.

filebuf * fpbase::rdbuf ( )

Returns a pointer to the current file buffer. Reimplemented in ifpstream, ofpstream, and fpstream.

void fpbase::setbuf ( char * buf, int len )

Allocates a buffer of size `len'.
