How to use vshKernelLoadExecVSHMs2 ?

Hi.

I´m developing an application that can launch some others. It run in kernel mode and, because that, i want to launch other app with kernel mode functions.

I heard about vsh functions like vshKernelLoadExecVSHMs2 and its sce equivalent sceKernelLoadExecVSHMs2. I think i have all the files i need, like "pspvshbridge.h" and "psploadexec_kernel.h", this are included in the proyect and makefile. I also fill the SceKernelLoadExecVSHParam structure which is passed to these functions but i have two results:

If i call sceKernelLoadExecVSHMs2, in spite of that function is defined in the include files listed up there, i get the error "undefined reference to sceKernelLoadExecVSHMs2" from compiler.

But, if i use vshKernelLoadExecVSHMs2 , the compilation is successful but, using psplink to execute the app, i get an error like "Can´t load module..." from pcterm command line. If i launch the application from the XMB, the psp freezes.

Thanks for any help.

You shouldn't really use the vsh* functions :)
As to the function not being there, try calling LoadExecForKernel_28D0D249() instead, as sometimes the SDK has those kind of names...

Thanks adrahil, that function works :)

The strange thing is that the compiler send the warning "implicit declaration of function 'LoadExecForKernel_28D0D249'". Maybe I´m not including the correct files?

Before your post i tried to execute the apps with sceKernelLoadExec and... it also works! so, somebody knows which is really the difference between sceKernelLoadExec and this other functions?

Sorry i forgot to mention, you indeed have to add "extern int LoadExecForKernel_28D0D249(...)" in your file, where in the "..." you put the params ^^

Not much.... they're each wrappers of each other with some layers added onto them...
