The following macro is defined in the header file. It may be best to include it via the header file, which is required by POSIX.
| Type | Macro |
|---|---|
| Idenfication | __BIONIC__ |
The following macros have to be included from the `` header file.
| Type | Macro | Description |
|---|---|---|
| Version | __GNU_LIBRARY__``__GNU_LIBRARY_MINOR__ |
Until version 5 |
| Version | __GLIBC__``__GLIBC_MINOR__ |
From version 6 |
Notice that the header file does not exist on all platforms, so it cannot be included without further ado. However, since it is included by other GNU glibc header files, a better way to obtain the above-mentioned macros is to include the header file (see e.g. paragraph 4/6 in ISO/IEC 9899:1999).
| Type | Macro | Format | Description |
|---|---|---|---|
| Identification | __KLIBC__ |
Zero is a valid value | |
| Version | __KLIBC__ |

| Version | __KLIBC_MINOR__ |

| Version | __KLIBC_PATCHLEVEL__ |

| Version | __CRTL_VER |
VVRREPPTT | VV = VersionRR = RevisionE = Edit numberPP = Patch (01 = A, ... 26 = Z)TT = Type (22 = official) |
Notice that I am not sure about the format of __CRTL_VER, but it seems to follow that of __VMS_VER.
