Overview

Random value generation in Symbian C++ can be done with the TRandom API. This calls into the OS to gen a pseudo random number stream based on the size of the supplied descriptor

This snippet can be self-signed.

MMP file

The following libraries are required:

LIBRARY euser.lib

Source file

#include <random.h>
 
int main (void)
{
// if we want 10 random bytes of data..
TBuf8<10> prngData;
prngData.SetLength( prngData.MaxLength() );
TRandom::RandomL(prngData);
 
// prngData now has the random data in it.
// Of course HBufC8* could be used to reduce stack space
return 0;
}

Postconditions

10 random numbers are generated
