341N/A
341N/A One can XSolarisIASetProceesInfo or XIASolarisGetProceesInfo.
341N/A Currently only passing process ids is supported.
341N/A
341N/A Of course QueryVersion and QueryExtension are supported.
341N/A
341N/A No support for error messages is involved. Yet. If this
341N/A interface becomes public this will need to be rewhacked
