# ReadBytes bank,file/stream,offset,count

# Parameters

bank = variable containing handle to valid bank file/stream = file handle of previously opened file or stream offset = offset in bytes to write the value count = how many bytes to write from the offset

# Description

You can read the contents of a disk file (or stream) to a memory bank using this command. Note: The file handle must be opened with OpenFile or OpenTCPStream and subsequently closed with CloseFile or CloseTCPStream after the reading operations are complete. Return how many bytes successfully read from a stream. Streams can only be used in Blitz Basic v1.52 or greater. See also: WriteBytes.

# Example

; Read/WriteBytes Commands Example
; Create a 50 byte memory bank
bnkTest=CreateBank(500)
; Let's fill the bank with random data
For t = 1 To 50
PokeByte bnkTest,t,Rnd(255)
Next
; Open a file to write to
fileBank=WriteFile("test.bnk")
; Write the bank to the file
WriteBytes bnkTest,fileBank,0,50
; Close it
CloseFile fileBank
; Free the bank
FreeBank bnkTest
; Make a new one
bnkTest=CreateBank(500)
; Open the file to read from
fileBank=OpenFile("test.bnk")
; Write the bank to the file
ReadBytes bnkTest,fileBank,0,50
; Close it
CloseFile fileBank
; Write back the results!
For t = 1 To 50
Print PeekByte (bnkTest,t)
Next
