| // Android fully supports 64-bit file offsets only for API 24 and above. |
| // |
| // Trying to define _FILE_OFFSET_BITS=64 for APIs below 24 |
| // leads to compilation failure for one or another reason, |
| // depending on target Android API level, Android NDK version, |
| // used STL, order of include paths and more. |
| // For more information, please see: |
| // - https://github.com/boostorg/filesystem/issues/65 |
| // - https://github.com/boostorg/filesystem/pull/69 |
| // |
| // Android NDK developers consider it the expected behavior. |
| // See their official position here: |
| // - https://github.com/android-ndk/ndk/issues/501#issuecomment-326447479 |
| // - https://android.googlesource.com/platform/bionic/+/a34817457feee026e8702a1d2dffe9e92b51d7d1/docs/32-bit-abi.md#32_bit-abi-bugs |
| // |
| // Thus we do not define _FILE_OFFSET_BITS in such case. |
| #else |
| // Defining _FILE_OFFSET_BITS=64 should kick in 64-bit off_t's |
| // (and thus st_size) on 32-bit systems that provide the Large File |
| // Support (LFS) interface, such as Linux, Solaris, and IRIX. |
| // |
| // At the time of this comment writing (March 2018), on most systems |
| // _FILE_OFFSET_BITS=64 definition is harmless: |
| // either the definition is supported and enables 64-bit off_t, |
| // or the definition is not supported and is ignored, in which case |
| // off_t does not change its default size for the target system |
| // (which may be 32-bit or 64-bit already). |
| // Thus it makes sense to have _FILE_OFFSET_BITS=64 defined by default, |
| // instead of listing every system that supports the definition. |
| // Those few systems, on which _FILE_OFFSET_BITS=64 is harmful, |
| // for example this definition causes compilation failure on those systems, |
| // should be exempt from defining _FILE_OFFSET_BITS by adding |
| // an appropriate #elif block above with the appropriate comment. |
| // |
| // _FILE_OFFSET_BITS must be defined before any headers are included |
| // to ensure that the definition is available to all included headers. |
| // That is required at least on Solaris, and possibly on other |
| // systems as well. |
