char far * far * buffer,
unsigned int length); Parameters
BufHandlePtr
- Output Parameter: Pointer to location where this
function will on success set a handle to the allocated buffer. This
handle is used internally by the @Chip-RTOS TCP/IP stack to manage the
subsequent release of this allocated buffer.
