Subject: [C ext to Ruby] variable args length and rb_class_new_instance

i did a first try calling rb_class_new_instance with variable args
length :

rosxutils.c: In function m_rfile_wo:
rosxutils.c:1870: error: parse error before [ token

1867 VALUE m_rfile_wo ( VALUE self,  VALUE file,  VALUE options )
1868 {
1869 	char *cfile = StringValuePtr ( file );
1870 	VALUE[2] args;
1871 	//VALUE args[2];
1872 	args[0] = file;
1873 	args[1] = options;
1874 	return rb_class_new_instance ( 2, &args, rb_path2class
( "RFile" ) );
1875 }

HERE i don't see where is the parse error ???


rosxutils.c: In function m_rfile_wo:
rosxutils.c:1874: warning: passing argument 2 of rb_class_new_instance
from incompatible pointer type

1867 VALUE m_rfile_wo ( VALUE self,  VALUE file,  VALUE options )
1868 {
1869 	char *cfile = StringValuePtr ( file );
1870 	//VALUE [2] args;
1871 	VALUE args[2];
1872 	args[0] = file;
1873 	args[1] = options;
1874 	return rb_class_new_instance ( 2, &args, rb_path2class
( "RFile" ) );
1875 }

AND HERE why the pointer is incompatible, because of the "&" ???
