EVP_DigestSign function

@RecordUse.new() @Native<Int Function(Pointer<EVP_MD_CTX>, Pointer<Uint8>, Pointer<Size>, Pointer<Uint8>, Size)>(ffi.Pointer<EVP_MD_CTX>, ffi.Pointer<ffi.Uint8>, ffi.Pointer<ffi.Size>, ffi.Pointer<ffi.Uint8>, ffi.Size)>(symbol: 'bssl_dart_EVP_DigestSign') int EVP_DigestSign(Pointer<EVP_MD_CTX> ctx, Pointer<Uint8> out_sig, Pointer<Size> out_sig_len, Pointer<Uint8> data, int data_len,)

EVP_DigestSign signs data_len bytes from data using ctx. If out_sig is NULL then *out_sig_len is set to the maximum number of output bytes. Otherwise, on entry, *out_sig_len must contain the length of the out_sig buffer. If the call is successful, the signature is written to out_sig and *out_sig_len is set to its length.

It returns one on success and zero on error.
