* be provided. In both cases, socket.c provides a __gnat_safe_getXXXbyYYY
|
204 |
|
|
* function with the same signature as getXXXbyYYY_r. If the operating
|
205 |
|
|
* system version of getXXXbyYYY is thread safe, the provided auxiliary

* buffer argument is unused and ignored.

*
|

|
|
* Target specific versions of GNAT.Sockets.Thin for platforms that can't
|
209 |

* fulfill these requirements must provide their own protection mechanism
|
210 |
|
|
* in Safe_GetXXXbyYYY, and if they require GNAT.Sockets to provide a buffer
|
211 |
|
|
* to this effect, then we need to set Need_Netdb_Buffer here (case of
|
212 |

|
* VxWorks and VMS).
