Synopsis: 1. `tcc4tcl::cproc ` 1. `` is the name of the Tcl procedure to create 1. `` is a list of arguments and their types for the C function; 1. The list is in the format of: type1 name1 type2 name2 ... typeN nameN 1. The supported types are: 1. Tcl_Interp*: Must be first argument, will be the interpreter and the user will not need to pass this parameter 1. int 1. long 1. float 1. double 1. char* 1. Tcl_Obj*: Passes the Tcl object in unchanged 1. void* 1. `` is the return type for the C function 1. The supported types are: 1. void: No return value 1. ok: Return TCL\_OK or TCL_ERROR 1. int 1. long 1. float 1. double 1. char*: TCL\_STATIC string (immutable from C -- use this for constants) 1. string, dstring: return a (char*) that is a TCL\_DYNAMIC string (allocated from Tcl\_Alloc, will be managed by Tcl) 1. vstring: return a (char*) that is a TCL\_VOLATILE string (mutable from C, will be copied be Tcl -- use this for local variables) 1. default: Tcl\_Obj*, a Tcl Object 1. `` is the C code that comprises the function Examples: 1. Create a Tcl procedure called "add" which accepts 2 integers (a, b) and returns a long: 1. `tcc4tcl::cproc add {int a int b} long { return(a+b); }` 2. Create a Tcl procedure called "mkdir" which accepts a Tcl_Obj* and returns a return code: 1. `tcc4tcl::cproc mkdir {Tcl_Interp* interp char* dir} ok { int mkdir_ret; mkdir_ret = mkdir(dir); if (mkdir_ret != 0) { Tcl_SetObjResult(interp, Tcl_NewStringObj("failed", -1)); return(TCL_ERROR); }; return(TCL_OK); }` tcc4tcl::ccode -------------- tcc4tcl::cdata -------------- Z 6bd114bf8e1fa9170e53cb18b36c4b31
