RE: [Xen-devel] where is the location of definition of "do_xen_version"?

["Zheng, Shaohui" <shaohui.zheng@xxxxxxxxx>]

tools/libxc/xc_private.h
the start line  is 88.
88 static inline int do_xen_version(int xc_handle, int cmd, void *dest)
 89 {
 90     DECLARE_HYPERCALL;
 91
 92     hypercall.op     = __HYPERVISOR_xen_version;
 93     hypercall.arg[0] = (unsigned long) cmd;
 94     hypercall.arg[1] = (unsigned long) dest;
 95
 96     return do_xen_hypercall(xc_handle, &hypercall);
 97 }

Ctags can help you find the definition a function.
Just run the following commands.
cd xen-src-dir
ctags -R
vim -t do_xen_version

then you got it.

Subject: [Xen-devel] where is the location of definition of "do_xen_version"?

hi, my friends:
Â
Currently, i am studying theÂway of hypercall's implementation.
i have already known the flow of hypercall's execuation, and i decided to add a 
new hypercall into the Xen.
first, i want to know the detail of one hypercall function, for example, 
"do_xen_version", but i can not find
the location of definition of "do_xen_version". who can help me?
Â
i have get some resualts as follows:
Â
[root@vt-0Âxen-3.1.0-src]#ÂfindÂ./Â-nameÂ"*.*"Â|ÂxargsÂgrepÂ"do_xen_version"
./xen/include/xen/hypercall.h:do_xen_version(

./tools/libxc/xc_private.h:staticÂinlineÂintÂdo_xen_version(intÂxc_handle,ÂintÂ
cmd,ÂvoidÂ*dest)
Â
but the "do_xen_version" is not in those above.
Â
thanks a lots.
