Dear Sir:
	I am sorry to trouble you, but this is important for me, and I need you
help, thank you very much.
	The problem is the following cod:
#include    <stdio.h>   
#include    <ctype.h>   
#include<stdlib.h>   
 #include    <stdarg.h>   
#include <string.h>

void msg(const char* type, ...)
{
	
	va_list ap;
	
	char* buf;
	va_start(ap,type);
	while(1) {
		char* arg = va_arg(ap, char*);
		if (arg == NULL || strcmp(arg, "") == 0) {
			printf("break...\n");
			break;
		}
		printf("----------%s------------\n",arg);
		//len += strnlen(arg, 200)+1;
	}
	
	va_end(ap);

}
   void    main(void)   
   {   
	msg("char","a","b","c","d");
   }   

when it is run in Red hat, the result is :
begin........
----------a------------
----------b------------
----------c------------
----------d------------
break...
but in solaris:
----------a------------
----------b------------
----------c------------
----------d------------
----------�    ا���|
------------
----------��
            �ZYX��]���------------
----------Z�2------------
----------����
------------
----------[�â------------
----------P
�������_
��1��n~------------
----------n    
�|�|�    ا���|
------------
----------�|
------------
----------[��------------
----------�z------------
break...
That means if the program is run in solaris, some problems will occur
like 'core dumped".I don't know how to resolve this problem. Of course
we  can add a parameter of the count of parameters and do something in a
for iterator, but there are many place to modify, so can you give me
some suggestions to resolve this problems in solaris environment? thank
you very much. I am looking forward to you reply.

The same problem is also occured in lib/mgmt/mgmt_common_lib.c
char*
mgmt_new_msg(const char* type, ...)
{
	va_list ap;
	int len;
	char* buf;
	
	/* count the total len of fields */	
	len = strnlen(type, MAX_STRLEN)+1;
	va_start(ap,type);
	while(1) {
		char* arg = va_arg(ap, char*);
		if (arg == NULL) {
			break;
		}
		len += strnlen(arg, MAX_STRLEN)+1;
	}
	va_end(ap);
	
	/* alloc memory */
	buf = (char*)mgmt_malloc(len+1);
	if (buf == NULL) {
		return NULL;
	}

	/* assign the first field */
	snprintf(buf,len,"%s", type);
	
	/* then the others */
	va_start(ap, type);
	while(1) {
		char* arg = va_arg(ap, char*);
		if (arg == NULL) {
			break;
		}
		strncat(buf, "\n", len);
		strncat(buf, arg, len);
	}
	va_end(ap);
	
	return buf;
}
