To Use The Sqlite Database To Save A Fixed Length Of Char Array, There May Be \0 And Other Characters In It, So As A String.
It is analogous to a char *. X = qbytearray(and) x.prepend(rock ). Unlike a qstring, a qbytearray has no encoding information and makes no attempt to decode bytes into.
Databuf = Qbytearray (Reinterpret_Cast<<Strong>Char</Strong>*> (Buf), 10);
It's just signedness issue, so this should work: Data () returns a pointer to the data stored in the byte array. Qbytearray is the qt class to store a array of bytes.
Qbytearray Provides The Following Basic Functions For Modifying The Byte Data:
The checksum is independent of the byte order. 即使更改为&port and&requestid，我也会得到正确的结果，因为char我不知道你刚才说了什么。 [qt]相关文章推荐 将qt小部件捕获为图像文件 qt opengl The checksum is independent of the byte order.
I++) { Buf[I] = (I + 1) % 3;//其中存在'\0'元素 } // 转化 Qbytearray Array;
(if for performance reasons you don't want to take a deep copy of the. Qbytearray ba = qbytearray::fromhex( 4142434445 ); Returns a hex encoded copy of the byte array.
Qbytearray Makes A Deep Copy Of The Const Char * Data, So You Can Modify It Later Without Experiencing Side Effects.
The pointer can be used to access and modify the bytes that compose the array. Returns the index position of the start of the last occurrence of byte ch in this byte. //给buf赋值 for (int i = 0;
