    13 Demonstrating P.I.P.S. Hybrid Applications</title><prolog><metadata><keywords/></metadata></prolog><conbody>

    14 <p>This example shows how to develop P.I.P.S. hybrid applications. The example

    15 uses both pure C and native Symbian C++ APIs. </p>

    19 of all available drives of the system. As P.I.P.S. APIs cannot be used to

    20 access these drives, native Symbian C++ APIs are used. The <codeph>RFs::Drive()</codeph> and <codeph>RFs::Volume()</codeph> APIs

    21 are used to access the drives and get their memory information. </p> <p>It

    22 displays the drive information by using the standard Input/Output functions

    23 defined in P.I.P.S. libraries. The <codeph>DescToChar()</codeph> function

    24 defined in the example converts the native Symbian descriptor strings to C

    25 strings. As the drive name is stored in a descriptor, the example uses this

    26 function to convert it to a C string. </p> </section>
