Using Qlibrary on a function that uses arguments

[schall_l]

Does someone has any experience or has any sample code on how using Qlibrary on a function that has arguments ?

The DLL source code is showing: (Note: I have the DLL only in a compiled form - so I cannot change it prototypes)

short int __stdcall About(unsigned char Device, unsigned char *Version,unsigned char *Manufact) {
...
}

So I've tried to do something like :

typedef short int (*About)(unsigned char, unsigned char *, unsigned char *);
 
unsigned char m_version[10];
unsigned char m_manufacturer[10];
 
Qlibrary m_dll("MyLibrary");
About about = (About) m_dll.resolve("About");
if (about) {
		about(0, m_version, m_manufacturer);
}

typedef short int (*About)(unsigned char, unsigned char *, unsigned char *);

unsigned char m_version[10];
unsigned char m_manufacturer[10];

Qlibrary m_dll("MyLibrary");
About about = (About) m_dll.resolve("About");
if (about) {
		about(0, m_version, m_manufacturer);
}

To copy to clipboard, switch view to plain text mode 

But the content in m_version and in m_manufacturer is not as expected.
