T-Kernel Specification (1.B0.02)

4.9. SYSTEM MANAGEMENT FUNCTIONS 203
prver is the version number of the T-Kernel implementation. The specific values assigned to prver are
left to the T-Kernel implementing vendor to decide.
prno is a return parameter for use in indicating T-Kernel product management information, product
number or the like. The specific meaning of values set in prno is left to the T-Kernel implementing
vendor to decide.
[Additional Notes]
The format of the packet and structure members for getting version information is mostly uniform across
the various TRON specifications, but the CPU information and variation descriptors are not specified.
The value obtained by tk ref ver in SpecVer is the first three digits of the specification version number.
The numbers after that indicate minor revisions such as those issued to correct misprints and the like,
and are not obtained by tk ref ver. For the purpose of matching to the specification contents, the first
three numbers of the specification version are sufficient.
An OS implementing a draft version may have A, B, or C as the second number of SpecVer. It must
be noted that in such cases the specification order of release may not correspond exactly to higher and
lower SpecVer values. For example, specifications may be released in the following order:
Ver 1.A1 → Ver 1.A2 → Ver 1.B1 → Ver 1.C1 → Ver 1.00 → Ver 1.01 → · · ·
In this example, when going from Ver 1.Cx to Ver 1.00, SpecVer goes from a higher to a lower value.
