1 | /* cygwin/config.h header file for Cygwin. |
| 2 | ||
| 3 | This wraps Cygwin configuration setting which were in newlib's | |
| ade47a34 | 4 | sys/config.h before. This way we can manaage our configuration |
| d3b450f3 CV |
5 | setting without bothering newlib. |

| 24 | /* The following provides an inline version of __getreent() for newlib, | |
| 25 | which will be used throughout the library whereever there is a _r | |
| 26 | version of a function that takes _REENT. This saves the overhead | |
| 27 | of a function call for what amounts to a simple computation. | |

29 | The definition below is essentially equivalent to the one in cygtls.h |
| 30 | (&_my_tls.local_clib) however it uses a fixed precomputed | |
| 31 | offset rather than dereferencing a field of a structure. | |
| 70300fdb | 32 | |
| 6e08b2f7 BD |
33 | Including tlsoffets.h here in order to get this constant offset |
| 34 | tls_local_clib is a bit of a hack, but the alternative would require | |
| 35 | dragging the entire definition of struct _cygtls (a large and complex | |
| 36 | Cygwin internal data structure) into newlib. The machinery to | |
| 37 | compute these offsets already exists for the sake of gendef so | |
| 38 | we might as well just use it here. */ | |
