WebJan 11, 2024 · Fastest way to extract n bytes from uint8_t buffer Ask Question Asked 5 years, 2 months ago Modified 5 years, 2 months ago Viewed 2k times 4 I work a lot with byte buffers and have to extract different parts. In this example, it's 4 byte, but it ranges from a single bit to 128 bit. Speed is the most important metric here. See the code for a MWE. WebMar 28, 2024 · It is the two's complement representation of -128 for 32-bit integers. The hex number 0x80 is interpreted as a negative integer, because QByteArray uses (signed) char to store bytes internally. Casting -128 to a quint32 yields the two's complement. The fix is to cast to quint8. auto b = static_cast(bytes[count - 1 - i]);
