Parameter |
Description |
dwSize |
Number of bytes with which to initialize the buffer. |
lpStr |
Character string to be copied to the buffer. |
lpData |
Pointer to data buffer to be copied. |
LBufferSrc |
A LEAD LBuffer object to copy. |
None.
LBuffer::LBuffer() is a constructor for the LBuffer class.
LBuffer::LBuffer(dwSize) will initialize the member variables and allocate the specified size of memory.
LBuffer::LBuffer(lpStr) will copy the specified string to the class object's buffer.
LBuffer::LBuffer(lpData, dwSize) will copy the specified buffer to the class object's buffer. This results in two copies of the buffer.
LBuffer::LBuffer(LBufferSrc) will copy the specified class object's buffer. This results in two copies of the buffer.
The parameter LBufferSrc is passed by reference, and is a required parameter.
