◆ GetLength()
|
static |
- Parameters
-
Length Gets the length field from the beginning of Data. This number is encoded into the output buffer. If the high order bit of the first byte is zero, then the remaining seven bits hold the actual length. If the high order bit is set then the remaining bits of that byte indicate how many bytes are used to hold the length. The subsequent bytes hold the actual length value. Data A pointer to current location for reading data. Length Used to store the length from the data stream.
- Returns
- Returns a pointer to the first byte after the length and stores the length value in Length.

◆ SetLength() [1/2]
|
static |
- Parameters
-
Length Sets the length field at the beginning of Data. This number is encoded into the output buffer. If the length is less than 128, it is written directly into the first byte. If 128 or more, the high order bit of the first byte is set and the remaining bits indicate how many bytes are needed to hold the length. The subsequent bytes hold the actual length. Data A pointer to current location for writing data. Length A number to encode into the data stream.
- Returns
- Returns a pointer to the first byte after the length.

static |
◆ CopyString()
|
static |
- Parameters
-
Data Copies the string at Data. Length The number of bytes to copy from Data. Data A pointer to current location for reading data.
- Returns
- Returns a pointer to a newly allocated string.

◆ GetString()
|
static |
- Parameters
-
Data Gets the string at Data. Upon return Length and Data represent the remaining data after the string has been copied off. [in,out] Length The number of bytes to copy from Data. Updated for the size of the string read. [in,out] Data A pointer to current location for reading data. Updated for the size of the string read.
- Returns
- Returns a pointer to a newly allocated string, or nullptr in case of error.
