Swig and PHP: C function expects enum as argument -

i have c function looks this:

getcurrentmode(radiomodes *radiomodes);  

and both .h file , swigs .i file contain these enum definition:

typedef enum _radiomodes {          radiomodes_none     = 0,          radiomodes_one  = 1,          radiomodes_two    = 2,  } radiomodes;  

getcurrentmode should set $rcs correct mode. when run:

$rcs = radiomodes_none; getcurrentmode($rcs);  

i these error: php fatal error: type error in argument 1 of getcurrentmode. expected swigtype_p__radiomodes

how swig , php set $rcs correct enum? or how swig convert enum radiomode int , back?

solved: issue needed add pointer function after .h file defined.

%pointer_functions( radiomodes, radiomodesp ) 

this added several new functions can use in php.
