BIN2U()

Convert unsigned long encoded bytes into Harbour numeric
---------------------------------------------------------------------------------

 Syntax

        BIN2U( <cBuffer> ) --> nNumber  

 Arguments

        <cBuffer>   is a character string that contain 32 bit encoded 
                  unsigned long integer (least significant byte first).
                  The first four bytes  are taken into account, the rest if
                  any are ignored.

 Returns

        BIN2U()   return numeric integer (or 0 if <cBuffer> is not a 
                  string).

 Description

      BIN2U() is one of the low level binary conversion functions, those
      functions convert between Harbour numeric and a character
      representation of numeric value. BIN2U() take four bytes of encoded
      32 bit unsigned long integer and convert it into standard Harbour
      numeric value.

      You might ask what is the need for such functions, well, first of
      all it allow you to read/write information from/to a binary file
      (like extracting information from DBF header), it is also a useful
      way to share information from source other than Harbour (C for
      instance).

      BIN2U() is the opposite of U2BIN()

 Examples

 
      // Show number of records in DBF
      FUNCTION main()
      LOCAL nHandle, cBuffer := space( 4 )
      nHandle := fopen( "test.dbf" )
      IF nHandle > 0
         fseek( nHandle, 4 )
         fread( nHandle, @cBuffer, 4 )
         ? "Number of records in file:", BIN2U( cBuffer )
         fclose( nHandle )
      ELSE
         ? "Can not open file"
      ENDIF
      RETURN NIL
 

Status

      Ready

 Compliance

      BIN2U() is an XBase++ compatibility function and does not exist  as a
      standard CA-Clipper 5.x function.  This function is only visible if
      source/rtl/binnum.c was compiled  with the HB_COMPAT_XPP flag.

 Files

      Library is rtl
