[Chicken-users] length of string in C code

[Heinrich Taube]

Hello,can someone please tell me how to turn something that is  
C_Stringp into either (1) A NULL terminated C string or (2) A buffer  
of chars plus the number of chars in the buffer?  from what i can tell  
by the docs it seems that a C_string is not null terminated. i could  
deal with that except i dont know how to determine its length.


if ( C_truep(C_blockp(w)) && C_truep( C_Stringp( w ) )) {
  int len = ???
  char* buf = ???
}


thanks for any help,
