# ReadInt (filehandle/stream)

# Parameters

filehandle/stream = a valid variable set with the OpenFile, ReadFile command, or OpenTCPStream (v1.52+) The value returned is an integer in the range -2147483648 to 2147483647

# Description

Once you've opened a disk file (or stream) for reading, use this command to read a single integer value from the file. Note, each value written uses 4 bytes of space and is written least significant byte first. Reading beyond the end of file does not result in an error, but each value read will be zero. Streams can only be used in Blitz Basic v1.52 or greater.

# Example

; Reading and writing a file using ReadInt and WriteInt functions
; Initialise some variables for the example
Int1% = 10 ; store 10
Int2% = 365 ; store 365
Int3% = 2147483647 ; store 2147483647 the largest positive Integer Value in BlitzBasic )
Int4% = - 2147483648 ; store -2147483648 the largest negative Integer Value in BlitzBasic )
; Open a file to write to
fileout = WriteFile("mydata.dat")
; Write the information to the file
WriteInt( fileout, Int1 )
WriteInt( fileout, Int2 )
WriteInt( fileout, Int3 )
WriteInt( fileout, Int4 )
; Close the file
CloseFile( fileout )
; Open the file to Read
filein = ReadFile("mydata.dat")
Read1 = ReadInt( filein )
Read2 = ReadInt( filein )
Read3 = ReadInt( filein )
Read4 = ReadInt( filein )
; Close the file once reading is finished
CloseFile( filein )
Print "Integer Data Read From File - mydata.dat "
Print Read1
Print Read2
Print Read3
Print Read4
