| rutz::stdiobuf::stdiobuf | ( | FILE * | f, | |
| int | om, | |||
| bool | throw_exception = false | |||
| ) |
Create with a reference to a FILE object.
The stdiobuf will NOT close the FILE on destruction, that is left up to the caller (since the caller must also have been the one to open the FILE object).
Definition at line 71 of file stdiobuf.cc.
| rutz::stdiobuf::stdiobuf | ( | int | fd, | |
| int | om, | |||
| bool | throw_exception = false | |||
| ) |
Create with a reference to a file descriptor.
The stdiobuf will NOT close the descriptor on destruction, that is left up to the caller (since the caller must also have been the one to open the file descriptor).

| rutz::stdiobuf::~stdiobuf | ( | ) | [inline] |
Destructor flushes buffer, but DOES NOT CLOSE the file descriptor.

References close().
| void rutz::stdiobuf::close | ( | void | ) |
Flushes the buffer and forgets the file descriptor, but DOESN'T CLOSE IT.
It is assumed that the same caller who passed the open file descriptor to our constructor will also eventually close that file descriptor.

| int rutz::stdiobuf::overflow | ( | int | c | ) | [virtual] |
Send more data to the underlying file descriptor.
Called when the streambuf's buffer has become full.

References is_open().
| int rutz::stdiobuf::sync | ( | ) | [virtual] |
Flush the current buffer contents to the underlying file.

Called when the streambuf's buffer has run out of data.
