Converting Descriptor to Char*

TBuf8 <200> fromBuf;
 
char*  toChar;

• First Way

Mem::Copy((char*)toChar,fromBuf.Ptr(),fromBuf.Length() );

• Second way

tochar = NULL;
tochar = (char *) malloc(fromBuf.Length()+1);
TInt index = 0;
for(index =0 ; index < fromBuf.Length(); index++)
{
  toChar[index] = fromBuf[index];
}
toChar[index] = 0;  //toChar contains the content

Converting Char* to Descriptor

TBuf8<200> toBuffer;
char* fromChar;

• First Way

TPtrC8 tempPtr8((TUint8 *)(fromChar));
HBufC* toBuffer = HBufC::NewLC(tempPtr8.Length());
toBuffer->Des().Copy(tempPtr8);     // toBuffer contains the content

• Second way

toBuffer.Copy(fromChar);

Note :- here basic conversion between Char and Buffer is given for conversion between different descriptors in symbian refer to this link
