Alternative method for setters & getters declaration

[GoogleCodeExporter]

In order to find setters and getters, the actual code depends on dlopen() and 
dlsym() to open the process as a shared library and to look for symbols.
However, this implies compiling with extra flags which not suitable for all 
projects.

I've made a simple wrapper around these calls so that a someone could replace 
this mecanism with a lookup table:

void *evcpe_symboldb_open(void);

void *evcpe_symboldb_find(void *handle, char *symbol); 
int evcpe_symboldb_close(void *handle);

/* -------------- EVCPE IMPLEMENTATION ------------*/
void *evcpe_symboldb_open(void)
{
   return dlopen(NULL, RTLD_LAZY|RTLD_GLOBAL);
}

void *evcpe_symboldb_find(void *handle, const char *symbol)
{
   return dlsym(handle, symbol);
}

int evcpe_symboldb_close(void *handle)
{
   return dlclose(handle);
}

/* -------------- SIMPLE LOOKUP TABLE ------------*/

struct entry_s
{
    void *fn; /**< function's ptr */
    const char *name; /**< function's name */
};

static struct entry_s methods[] = 
{
  /* ............... */

};

void *evcpe_symboldb_open(void)
{
   return 0;
}

void *evcpe_symboldb_find(void *handle, const char *symbol)
{
    int i;

    for (i = 0; i < sizeof(methods)/sizeof(struct entry_s); ++i)
    {
       if (!strcmp(methods[i].name, symbol))
       {
          return 0;
       }
    }

    return -1;
}

int evcpe_symboldb_close(void *handle)
{
   return 0;
}
