5 // This header file describes the BoringCrypto ABI as built for use in Go.
6 // The BoringCrypto build for Go (which generates goboringcrypto_*.syso)
7 // takes the standard libcrypto.a from BoringCrypto and adds the prefix
8 // _goboringcrypto_ to every symbol, to avoid possible conflicts with
9 // code wrapping a different BoringCrypto or OpenSSL.
10 //
11 // To make this header standalone (so that building Go does not require
12 // having a full set of BoringCrypto headers), the struct details are not here.
13 // Instead, while building the syso, we compile and run a C++ program
14 // that checks that the sizes match. The program also checks (during compilation)
15 // that all the function prototypes match the BoringCrypto equivalents.
16 // The generation of the checking program depends on the declaration
17 // forms used below (one line for most, multiline for enums).
18
19 #include <stdlib.h> // size_t
20 #include <stdint.h> // uint8_t
21
22 // This symbol is hidden in BoringCrypto and marked as a constructor,
23 // but cmd/link's internal linking mode doesn't handle constructors.
24 // Until it does, we've exported the symbol and can call it explicitly.
25 // (If using external linking mode, it will therefore be called twice,
26 // once explicitly and once as a constructor, but that's OK.)
