  16.      The _ssss_yyyy_ssss_cccc_oooo_nnnn_ffff function provides a method for an application to determine
  17.      the current value of a configurable system limit or option (variable).
  18.      By using this function, applications can be more portable across
  19.      different operating systems.
  20.  
  21.      The _n_a_m_e argument represents the system variable to be queried.  Some of
  22.      the limits have a minimal value defined by POSIX or XPG4 which may have a
  23.      higher value under IRIX.  Some limits are fixed in the system and some
  24.      may be altered by the system administrator (see ssssyyyyssssttttuuuunnnneeee(1M) for
  25.      information on how to change system limits).  In general, the values
  26.      returned by ssssyyyyssssccccoooonnnnffff will be constant for the duration of a process.  In
  27.      various manual pages, limits are specified within braces (e.g. {_A_R_G__M_A_X}.
  28.      The limit name, prepended with a ______SSSS_CCCC_____ is the name to be used with
  29.      _ssss_yyyy_ssss_cccc_oooo_nnnn_ffff.  For options such as {_P_O_S_I_X_2__V_E_R_S_I_O_N}, the name to be used as
  30.      the argument to _n_a_m_e is the option name, minus _PPPP_OOOO_SSSS_IIII_XXXX and ______SSSS_CCCC_____ prepended
  31.      (______SSSS_CCCC______2222______VVVV_EEEE_RRRR_SSSS_IIII_OOOO_NNNN).  The following lists the set of system variables from
  32.      _<<<<_uuuu_nnnn_iiii_ssss_tttt_dddd_...._hhhh_>>>> that can be returned by _ssss_yyyy_ssss_cccc_oooo_nnnn_ffff.
