Example
// Extract integer at byte 52 from the test.raw file
 
// Load buffer that corresponds to the test.raw file
bMyBuffer is Buffer = fLoadBuffer("C:\Test\test.raw")
// Check loading
IF bMyBuffer = "" THEN
Error("Error reading buffer")
RETURN
END
// Extract integer at byte 52
nMyInteger is int = BufferToInteger(bMyBuffer, 52)
Syntax
<Result> = BufferToInteger(<Buffer to use> [, <Position> [, <Number of bytes to read>]])
<Result>: Integer
Integer extracted from the buffer.
<Buffer to use>: Buffer
Name of the buffer variable loaded in memory containing the integer. This parameter can also correspond to an Ansi or Unicode string.
<Position>: Optional integer
Position at which the integer will be searched. The first position of the buffer corresponds to 0.
By default, <Position> is set to 0.
<Number of bytes to read>: Optional integer
Number of bytes on which the integer is encoded. The value of this parameter can be set to 1, 2, 4 or 8.
By default, <Number of bytes to read> is set to 4.
Remarks
  • By default, the integer is read at the beginning of the buffer as an unsigned 4-byte integer (32 bits).
  • The bytes are read in Little-Endian mode (the low byte is read first).
