Are there known bugs when passing Eu values to C_FLOAT ? I have several routines in EuGTK which worked fine with Eu 3, but no longer work properly now with 4.0. Each of these routines has one thing in common, they pass floats to c_func or c_proc.
I don't think so. Can you post some more details? I did this test:
// irv.c
// build with: $ gcc -shared -fPIC -ldl irv.c -o irv.so
#include <stdio.h>
void test_float( double foo, float bar ){
printf( "double: %f\nfloat: %f\n", foo, bar );
}
...and then called it using:
-- irv.ex include std/dll.e constant irv = open_dll( "./irv.so" ), test_float = define_c_proc( irv, "test_float", {C_DOUBLE, C_FLOAT}) c_proc( test_float, { 0.25, 0.75})
Then I get:
$ eui irv double: 0.250000 float: 0.750000
So it looks good to me.
