For the instance domain _i_n_d_o_m, in the current Performance Metrics
Application Programming Interface (PMAPI) context, locate the instance
with the external identification given by _n_a_m_e, and return the internal
instance identifier.
Only the leading non-space characters of _n_a_m_e will be used to identify
the instance.
The value for the instance domain _i_n_d_o_m is typically extracted from a
_p_m_D_e_s_c structure, following a call to ppppmmmmLLLLooooooookkkkuuuuppppDDDDeeeesssscccc(3) for a particular
performance metric.
ppppmmmmLLLLooooooookkkkuuuuppppIIIInnnnDDDDoooommmm will return a positive instance identifier on success.
