FileBuf()
Constructor.
Definition FileBuf.cpp:56
FileBuf * close()
If isOpen() == false, returns a null pointer.
Definition FileBuf.cpp:181
FileBuf * open(FILE *fp)
If isOpen() == true, returns 0, otherwise initializes the FileBuf to use fp.
Definition FileBuf.cpp:74
The purpose of this class is to provide an alternative implementation of std::ifstream that is based ...
IFileStream * close()
If isOpen() == false, returns a null pointer.
IFileStream * open(FILE *fp)
If isOpen() == true, returns 0, otherwise initializes the IFileStream to use fp.
Taken from RFC 1321.
AutoResource< AutoDescriptorPolicy > AutoDescriptor
An analog of std::auto_ptr for descriptors.
