i’d like to use ruby symbols from C , i’ve found ID2SYM and SYM2ID but  
nothing like STR2SYM in ruby.h

i’d like to produce those ruby symbols :

:verbose and : noop

from C side…

i’m able to retrieve, from C side, the value of a key provided i know,  
in advance the key and the key is a string…

ID2SYM( rb\_intern( “verbose” ) );  
ID2SYM( rb\_intern( “noop” ) );
