C++ (Cpp) encoding_ord_error示例

示例#1

文件： ucs4.c 项目： biddyweb/parrot

static UINTVAL
ucs4_ord(PARROT_INTERP, ARGIN(const STRING *src), INTVAL idx)
{
    ASSERT_ARGS(ucs4_ord)
    const utf32_t * const ptr = (utf32_t *)src->strstart;
    const UINTVAL         len = src->strlen;

    if (idx < 0)
        idx += len;

    if ((UINTVAL)idx >= len)
        encoding_ord_error(interp, src, idx);

    return ptr[idx];
}

示例#2

文件： utf8.c 项目： Cristofor/parrot

static UINTVAL

{
    ASSERT_ARGS(utf8_ord)
    const UINTVAL len = STRING_length(src);
    const utf8_t *start;

    if (idx < 0)
        idx += len;

    if ((UINTVAL)idx >= len)
        encoding_ord_error(interp, src, idx);

    start = utf8_skip_forward((utf8_t *)src->strstart, idx);

    return utf8_decode(interp, start);
