Hi Ben,
You can call NSS_NoDB_Init(NULL), until your application needs
to store certificates or private keys persistently in NSS databases.
The reason your NSS_Init(NULL) call fails is that you're passing
a NULL pointer to NSS_Init. Instead, you should pass a string
that represents the pathname of the directory where you want
to store your NSS databases.
PR_GetErrorText is essentially an obsolete function now because
it isn't adopted by NSPR clients. Call PR_GetError instead to get
an error code, and look it up at
