OpenSSL win error Openssl_uplink (58d46000,08): No Openssl_applink

Python uses M2crypto to read and write files, always quote:

Openssl_uplink (58d46000,08): No Openssl_applink

Functions related to file IO cannot be directly manipulated when using OpenSSL under the Windows platform. Because MS/UPLINK.C will get the MS/APPLINK.C function table dynamically from the current EXE, the logic is

void Openssl_uplink (volatile void **table, int index)
{
HANDLE h = getmodulehandle (NULL) GetProcAddress (H, "Openssl_applink") }

。 If you want to use it, you must also link MS/UPLINK.C when you link the exe. When Python uses m2crypto, if you manipulate the file, you can first create a Memorybuffer BIO object, and then read Memorybuffer as a string and manually write the string to the file.
