[Xenomai-help] 答复: uITRON skin problem

[qhuanj <qiuhj@domain.hid>]

Thank you for your reply

I wrote a sample，code as below
#include	<uitron/uitron.h>
#include 	<dlfcn.h>
ER (*crtsk)(ID tskid,T_CTSK *pk_ctsk);

void		Pf_ent_tsk(int code)
{
}
int main()
{
	T_CTSK	pk_ctsk;	
	int status;
	void *uitronlib;
	const char *dlError = 0;
	
///////////////////////////
	uitronlib = dlopen("/usr/xenomai/lib/libuitron.so", RTLD_LAZY); 
       <<- Xenomai uITRON skin init:shd_tsk() failed, status -33
///////////////////////////	
	dlError = dlerror();
	printf("open erro -- >%s \n", dlError);
	if(dlError) exit(1);
	crtsk = dlsym(uitronlib, "cre_tsk");
	dlError = dlerror();
	printf("sym error -- >%s \n", dlError);
	if(dlError)
	{
		dlclose(uitronlib);
		exit(1);
	}
	pk_ctsk.exinf	= (void*)0;
	pk_ctsk.task	= (FPTR)Pf_ent_tsk;
	pk_ctsk.tskatr	= (ATR)(0);
	pk_ctsk.itskpri	= 0;
	pk_ctsk.stksz	= 0;
	status = (*crtsk)( 1, &pk_ctsk );
}
I found that this error code was in the file of src/skins/uitron/Init.c.
"shd_tsk" was called in the "__init_xeno_interface" , but
"__init_xeno_interface" was called by system Automaticly, I can not find any
err.
Hope your help

So you already know that an invalid parameter was sent to the routine,
right?

Any code from your end to help us understand what might fail on our end?

uITRON is a public spec. If you meant "any doc for the Xenomai uITRON
skin implementation", then -ENOPARSE. "Documentation"? No idea what it
is, sorry.

PS: please refrain from posting to xenomai-core for such inquiries in
the hope of getting an answer faster, you won't get help this way, it
was in fact "that close" to be counter-productive. As stated here:
http://www.xenomai.org/index.php/Main_Page
xenomai-help is the perfect list for this question.
