func sid
Returns the space ID (SID) portion of a virtual or extended address.
Syntax
sid ( virtaddr )
The SID function returns the space ID portion of a virtual address.
If the parameter
virtaddr is a short pointer (SPTR) it is internally converted to a long
pointer by the STOL function, and the resulting SID portion is returned.
If the parameter
virtaddr is a long pointer or an extended address, the SID portion is
simply extracted and returned.
Formal Declaration
sid:u32 ( virtaddr :ptr)
Parameters
virtaddr The virtual address from which the space ID (SID) portion is returned.
Virtaddr can be a short pointer, a long pointer, or an extended address.
