Technical field
The present invention relates to the function call technology, more particularly, relate to a kind of function calling method and device.
Background technology
Dynamic link library is the concept development from C language function library and Pascal library unit, is the executable file as the Sharing Function storehouse.Dynamic link provides a kind of method, makes process can call the function that does not belong to its executable code.The executable code of function is positioned among the DLL (Dynamic LinkLibrary, dynamic link library), this DLL comprise one or more by compiling, link and with the function of the process separate storage of using them.DLL also helps shared data and resource.A plurality of application programs are the content of single DLL copy in the access memory simultaneously.Can be interpreted as a function library to dynamic link library, this function library has comprised global data, the function that compiled and resource.Dynamic link library can not direct operation as common executable file, but is used for for other exe file (executable file) or dll file the Sharing Function storehouse being provided.DLL is loaded in the predetermined base address through after compiling, if conflict with other DLL, file just is mapped on the virtual address identical in the process.Different with static library is that it can not directly be linked in the executable file, but when program run, just loads.The dynamic link library of a plurality of application programs in can shared drive so just saved the spending of internal memory greatly, and can have been reduced the size of executable file effectively.
Dynamic link library generally comprises .lib (derivative function) .h .DLL file.Dynamic link library has following two kinds of method of application:
A. implicit expression link, static library is similar with using, and is divided into for three steps: quote .lib, comprise header file, use derivative function;
B. dynamic load directly uses LoadLibrary to load required dynamic base, specifies required derivative function then.
Said method can only call the function of deriving among the DLL.If have some functions to realize our desired function among the DLL, but can't derive separately, then we can't use these functions separately.
