| 4 | `config.h` was split into `build_info.h` and `mbedtls_config.h`. |
| 5 | `build_info.h` is intended to be included from C code directly, while |

| Bence Szépkúti | 90b79ab | 2021-06-04 00:19:53 +0200 | [diff] [blame] | 7 | change the build configuration, and should generally only be included from |
| 8 | `build_info.h`. This is because all the preprocessor logic has been moved |
| 9 | into `build_info.h`, including the handling of the `MBEDTLS_CONFIG_FILE` |
| 10 | macro. |

| Bence Szépkúti | 36da4cc | 2021-06-21 17:14:41 +0200 | [diff] [blame] | 12 | Config file symbols `MBEDTLS_CONFIG_VERSION` and `MBEDTLS_USER_CONFIG_VERSION` |
| 13 | were introduced for use in `MBEDTLS_CONFIG_FILE` and |
| 14 | `MBEDTLS_USER_CONFIG_FILE` respectively. |
| 15 | Defining them to a particular value will ensure that mbedtls interprets |
| 16 | the config file in a way that's compatible with the config file format |
| 17 | indicated by the value. |
| 18 | The config file versions are based on the value of `MBEDTLS_VERSION_NUMBER` |
| 19 | of the mbedtls version that first introduced that config file format. |
| 20 | The only value currently supported is `0x03000000`. |
