Simple Example

set handle [tcc4tcl::new]
$handle cproc add {int a int b} long { return(a+b); }
puts [add 1 2]

Example 1: mkdir

#! /usr/bin/env tclsh

package require tcc4tcl

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);
}

Example 2: curl

#! /usr/bin/env tclsh

package require tcc4tcl

set handle [tcc4tcl::new]

$handle ccode {
#include <stdint.h>
#include <curl/curl.h>
}
$handle cwrap curl_version {} vstring
$handle cproc curl_fetch {char* url} ok {
        void *handle;

        handle = curl_easy_init();
        if (!handle) {
                return(TCL_ERROR);
        }

        curl_easy_setopt(handle, CURLOPT_URL, url);
        curl_easy_perform(handle);

        return(TCL_OK);
}
