<p>In typical cases the threads can't access to each others memory areas. However, interthread communication provides a way to read and write to other threads memory. The memory address given for reading or writing must be a descriptor. The actual reading and writing is done by kernel that will make sure that descriptor constraints are respected: buffer is not read or written before its starting index or after end index.</p> |

<p>Function demonstrates different usages of RBuf. It should be noted that the Create and Assign functions leak memory if the memory for the RBuf isn't freed (i.e calling Close()) before calling them. RBuf was introduced in Symbian OS 9 but was backported to Symbian OS 8. </p> |
