 163  * operations be either thread safe, or that a reentrant version getXXXbyYYY_r

 166  * system version of getXXXbyYYY is thread safe, the provided auxiliary
 167  * buffer argument is unused and ignored.
 168  *
 169  * Target specific versions of GNAT.Sockets.Thin for platforms that can't
 170  * fulfill these requirements must provide their own protection mechanism
 171  * in Safe_GetXXXbyYYY, and if they require GNAT.Sockets to provide a buffer
 172  * to this effect, then we need to set Need_Netdb_Buffer here (case of
 173  * VxWorks and VMS).
