Beispiel #1

Datei: String8.cpp Projekt: Eason-Xi/ph-open

static char* allocFromUTF32(const char32_t* in, size_t len)
{
    if (len == 0) {
        return getEmptyString();
    }

    const ssize_t bytes = utf32_to_utf8_length(in, len);
    if (bytes < 0) {
        return getEmptyString();
    }

    SharedBuffer* buf = SharedBuffer::alloc(bytes+1);
    if (!buf) {

    }

    char* str = (char*) buf->data();
    utf32_to_utf8(in, len, str);

    return str;
}
