57 * Applications should use -DOPENSSL_API_COMPAT=<version> to suppress the
58 * declarations of functions deprecated in or before <version>. If this is
59 * undefined, the value of the macro OPENSSL_API_MIN above is the default.
61 * For any version number up until version 1.1.x, <version> is expected to be
62 * the calculated version number 0xMNNFFPPSL. For version numbers 3.0.0 and
63 * on, <version> is expected to be only the major version number (i.e. 3 for

77 * We convert the OPENSSL_API_COMPAT value to an API level. The API level
78 * is the major version number for 3.0.0 and on. For earlier versions, it
79 * uses this scheme, which is close enough for our purposes:
81 * 0.x.y 0 (0.9.8 was the last release in this series)
82 * 1.0.x 1 (1.0.2 was the last release in this series)
83 * 1.1.x 2 (1.1.1 was the last release in this series)
