GetLastError returns the error code of 1114
After testing is like this:
In continuous circulation call LoadLibrary () is unable to load the DLL anymore after more than 80 times,
But each LoadLibrary () before calling FreeLibrary release can infinite loading, but doing so is against original intention, could you tell me how to break this problem?

CodePudding user response:

WinError. H: # define ERROR_DLL_INIT_FAILED 1114 l

CodePudding user response:

Load the same DLL, the DLL initialization stem what

load the same DLL, the DLL initialization dry what

Is not the same DLL loading, loading of different DLL has different use, should be no call FreeLibrary release, but the DLL is useless over can't release,

CodePudding user response:

A problem is always a DLL? Or random

CodePudding user response:

refer to 7th floor Dobzhansky response:

problem is always a DLL? Or random

Is to load the DLL number problem, if not call FreeLibrary release DLL loaded, loaded number is limited

CodePudding user response:

reference 1st floor zgl7903 response:

whether memory/resources? GetLastError see error code

When I call FreeLibrary release DLL loaded, you can load an infinite number of DLL,
Is the insufficient memory resources? But this place can not release, the problem how to break?

CodePudding user response:

In the real world, in addition to the time and space could be infinite, any other things are limited,
