+** PR_GetRandomNoise() -- Get random noise from the host platform
+**
+** Description:
+** PR_GetRandomNoise() provides, depending on platform, a random value.
+** The length of the random value is dependent on platform and the
+** platform's ability to provide a random value at that moment.
+**
+** The intent of PR_GetRandomNoise() is to provide a "seed" value for a
+** another random number generator that may be suitable for
+** cryptographic operations. This implies that the random value
+** provided may not be, by itself, cryptographically secure. The value
+** generated by PR_GetRandomNoise() is at best, extremely difficult to
+** predict and is as non-deterministic as the underlying platfrom can
+** provide.
+**
+** Inputs:
+**   buf -- pointer to a caller supplied buffer to contain the
+**          generated random number. buf must be at least as large as
+**          is specified in the 'size' argument.
+**
+**   size -- the requested size of the generated random number
+**
+** Outputs:
+**   a random number provided in 'buf'.
+**
+** Returns:
+**   PRSize value equal to the size of the random number actually
+**   generated, or zero. The generated size may be less than the size
+**   requested. A return value of zero means that PR_GetRandomNoise() is
+**   not implemented on this platform, or there is no available noise
+**   available to be returned at the time of the call.
+**
+** Restrictions:
+**   Calls to PR_GetRandomNoise() may use a lot of CPU on some platforms.
+**   Some platforms may block for up to a few seconds while they
+**   accumulate some noise. Busy machines generate lots of noise, but
+**   care is advised when using PR_GetRandomNoise() frequently in your
+**   application.
+**
+** History:
+**   Parts of the model dependent implementation for PR_GetRandomNoise()
+**   were taken in whole or part from code previously in Netscape's NSS
+**   component.
