OverbyteIcsLIBEAY.pas: EVP_PKEY_paramgen() pkey parameter should be double pointer

[Ralf Junker 1]

EVP_PKEY_paramgen() pkey should be a double pointer parameter. OverbyteIcsLIBEAY.pas line 1752, SVN 2063:

f_EVP_PKEY_paramgen: function(pctx: PEVP_PKEY_CTX; pkey: PEVP_PKEY): Integer; cdecl = Nil;

Notice the two ** asterisks in the OpenSSL's evp.h C declaration:

int EVP_PKEY_paramgen(EVP_PKEY_CTX *ctx, EVP_PKEY **ppkey);

Possible fixes:

{ More C like: Better if ppkey may be nil. }
f_EVP_PKEY_paramgen: function(pctx: PEVP_PKEY_CTX; ppkey: PPEVP_PKEY): Integer; cdecl = Nil;

{ More Pascal like. Notice that nil cannot be passed this way. }
f_EVP_PKEY_paramgen: function(pctx: PEVP_PKEY_CTX; var pkey: PEVP_PKEY): Integer; cdecl = Nil;
