The Sun::Solaris::Exacct module provides constants from the various exacct header files. The P_PID, P_TASKID, P_PROJID and all the EW_*, EP_*, EXR_* macros are extracted during the module build process. The macros are extracted from the exacct header files under /usr/include and provided as Perl constants. Constants passed to the Sun::Solaris::Exacct functions can either be an integer value such as. EW_FINAL or a string representation of the same variable such as. “EW_FINAL”.
