StrUtils.MidBStr Function

Pascal

Description

MidBStr returns a substring AByteCount bytes beginning at AByteStart bytes.

If AByteStart is larger than the length of AText in bytes, MidBStr returns an empty string.

If AByteCount specifies more bytes than are available, only the available bytes are returned.

Note: MidBStr assumes all characters are one byte long, and does not behave correctly if AText contains multi-byte characters. To handle all strings correctly, use MidStr.
