C++ (Cpp) ErrnoHolder Examples

Example #1

File: memory.cpp Project: Zaneris/emu-ex-plus-alpha

void *MDFN_realloc_real(bool dothrow, void *ptr, uint32 size, const char *purpose, const char *_file, const int _line)
{
    void *ret;

    ret = realloc(ptr, size);

    if(!ret)
    {
        if(dothrow)
        {
            ErrnoHolder ene;

            throw MDFN_Error(ene.Errno(), _("Error allocating(realloc) %u bytes for \"%s\" in %s(%d)!"), size, purpose, _file, _line);
        }
        else
        {
            MDFN_PrintError(_("Error allocating(realloc) %u bytes for \"%s\" in %s(%d)!"), size, purpose, _file, _line);
            return(0);
        }
    }
    return ret;
}

Example #2

File: error.cpp Project: aliaspider/beetle-psx-libretro

MDFN_Error::MDFN_Error(const ErrnoHolder &enh)
{
   errno_code = enh.Errno();

   error_message = strdup(enh.StrError());
}

Example #3

File: error.cpp Project: CatalystG/mednafen-libretro

MDFN_Error::MDFN_Error(const ErrnoHolder &enh)
{
   errno_code = enh.Errno();

   error_message = trio_aprintf("%s", enh.StrError());
}

Example #4

File: error.cpp Project: Rakashazi/emu-ex-plus-alpha

MDFN_Error::MDFN_Error(const ErrnoHolder &enh)
{
 errno_code = enh.Errno();

 asprintf(&error_message, "%s", enh.StrError());
}
