std::streambuf |
| Name | Description |
|---|---|
FixedMemOutStreamBuf [constructor] | Create an empty stream buffer that uses the specified character buffer of the specified length. The behavior is undefined unless length == 0 or length > 0 && buffer != 0. Note that buffer is held but not owned. |
~FixedMemOutStreamBuf [destructor] [virtual] | Destroy this stream buffer. |
capacity | Return the number of characters in the buffer held by this stream buffer. See length, below, for the span of bytes actually written. |
data | Return a pointer providing modifiable access to the character buffer held by this stream buffer (supplied at construction). |
data | Return a pointer providing non-modifiable access to the character buffer held by this stream buffer (supplied at construction). |
length | Return the number of characters from the beginning of the buffer to the current write position. This function returns the same value as seekoff(0, bsl::ios_base::end). The length is modified by a call to seekpos or seekoff and reset to zero by a call to pubsetbuf. |
| Name | Description |
|---|---|
seekoff [virtual] | Set the position indicator to the relative specified offset from the base position indicated by the specified fixedPosition and return the resulting absolute position on success or pos_type(-1) on failure. Optionally specify which area of the stream buffer. The seek operation will fail if which does not include the flag bsl::ios_base::out or if the resulting absolute position is less than zero or greater than the value returned by length. |
seekpos [virtual] | Set the position indicator to the specified position and return the resulting absolute position on success or pos_type(-1) on failure. Optionally specify which area of the stream buffer. The seekpos operation will fail if which does not include the flag bsl::ios_base::out or if position is less then zero or greater than the value returned by length. |
