Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is a part of embodiment of the present invention, instead of whole embodiment.Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art obtain under the prerequisite not making creative work, all should belong to the scope of protection of the invention.
To facilitate understanding of the present embodiment of the invention, first introduce during the embodiment of the present invention describes at this several key elements that can introduce.
Operational factor is transmitted: so-called operational factor transmission refers to the Main function in the programming languages such as C/C++, often with parameter argc, argv, such as, Main function int Main (int argc, char**argv) and int Main (int argc, char*argv []) in, the effect of parameter argc, argv comprises: argc is used for the number (separating with blank character) of the capable input parameter of memory command, and argv is for storing all command line parameters.Might as well suppose that executable program is hello.exe, if run this program in order line, and operation catalogue is this program place catalogue, action command is: " hello.exe hello world ", then now the value of argc is 3, argv [0] is " hello.exe ", and argv [1] is " hello ", and argv [2] is " world ".
Emulator: (simulator), its software is called simulation softward, refer to and make computing machine or other multimedia platforms (palm PC, mobile phone) that software on other platforms can be run mainly through the function of software simulation hardware processor and the program of order set.
Libc:Libc is the function library of the ANSI C under Linux.ANSI C is basic C language function library, contains the built-in function that C language is the most basic.
Serial ports (Serial Port): serial port, an input/output end port (passage), it can receive data in the mode of each from the CPU of computing machine or communication facilities or send data to them.Serial port is used for the interface of serial data communication and much peripherals, as: mouse and printer.
Joint test behavior tissue (Joint Test Action Group, JTAG): a tissue be made up of the electronics manufacturer that a few family is main, object is to formulate printed circuit board (Printed Circuit Board, PCB) plate and integrated circuit (Integrated Circuit, IC) standard.JTAG is commonly used to the international standard test protocol representing that this tissue proposes, and is mainly used in chip internal test.
Linking format (Executable and Linkable Format, ELF) can be performed: be the binary file format standard of the class Unix operating system on x86 framework.Because of its extensibility and dirigibility, also can be applicable in the operating system of other processor, computer system architecture.The part of some storage programs and data is comprised, the section of being called in Elf file.Wherein program segment preserves binary program, and data segment is used for global variable and the static variable of save routine.
More current base band veneers need to support multimode networks such as () UMTS, LTE, need the mode being passed ginseng by application program to specify to start which kind of network when starting veneer.Such as pass through-LTE option and specify startup LTE network.
When testing veneer application program and veneer, need to test for different scene.If support application program main function does not pass ginseng, need to compile often kind of test scene, build corresponding veneer application testing program.
After supporting veneer application program Parameter transfer, test scene can be controlled flexibly by veneer application journey main function parameter, only need compiling once, just can be controlled the application scenarios of test afterwards by command line parameter, and flexible parameter configuration can be carried out to test scene.
Fig. 1 is the method flow diagram of embodiment of the present invention Parameter transfer.The method of Fig. 1 is performed by veneer loader.
101, call instruction line parameter.
Wherein, this command line parameter carries the operational factor of executable program mark and this executable program.

For loader C: app the call instruction of Helloword-argument " argv0 argv1 ".One section of false code realized and step thereof illustrate specific as follows:
// definition data pointer points to self-defining data section
char*ptr_mem＝arg_data_seg_addr；
// remarks: in internal memory, first three long of supplemental characteristic section preserves argc respectively, argv [0] address, argv [1] address
// 1. memory parameters data segment first addresss preserve the value of argc
((long*)ptr_mem)[0]＝(long)2；
The address of // 2. preservations argv [0]
((long*)ptr_mem)[1]＝ptr_mem+sizeof(long)*3；
The address of // 3. preservations argv [0]
((long*)ptr_mem)[2]＝ptr_mem+sizeof(long)*3+length(argv[0])；
The value of // 4. preservations argv [0]
strcpy(ptr_mem+sizeof(long)*3,argv[0])；
The value of // 5. preservations argv [1]
strcpy(ptr_mem+sizeof(long)*3+length(argv[0]),argv[1])；
