thank you very much it works
here is slightly modified code (it compiled for C)
#include <mach-o/dyld.h>
#include <mach-o/ldsyms.h> //defines _mh_dylib_header see man page for
ld
void foo ()
{
int i;
struct mach_header* header = &_mh_dylib_header;
const char* imagename = 0;
int cnt = _dyld_image_count();
for (i = 1; i < cnt; i++) {
if (_dyld_get_image_header(i) == header)
imagename = _dyld_get_image_name(i);//contains absolute
path to dylib
}
if(imagename != NULL) printf("dylib path is %s\n",imagename);
//contains
}
thanks again
