[sv-cc] DPI import function properties - pure, context, none

Imported DPI function can be done in three different ways

import "DPI-C" *pure *function void uvm_rgm_set_hdl();- pure, VPIcannot
be used
import "DPI-C" *context *function void uvm_rgm_set_hdl();- context is
automatically set for VPI usage
import "DPI-C" function void uvm_rgm_set_hdl(); - function with no
context and no pure ????

My question is what is the difference between function which has neither
pure nor context used in import and context function?
Can VPI calls be done inside?
