RWARRAY(3)                 GNU Awk Extension Modules                RWARRAY(3)



NAME
       writea, reada - write and read gawk arrays to/from files

SYNOPSIS
       @load "rwarray"

       ret = writea(file, array)
       ret = reada(file, array)

DESCRIPTION
       The  rwarray extension adds two functions named writea().  and reada(),
       as follows.

       writea()
              This function takes a string argument, which is the name of  the
              file to which dump the array, and the array itself as the second
              argument.  writea()  understands  multidimensional  arrays.   It
              returns one on success, or zero upon failure.

       reada()
              is the inverse of writea(); it reads the file named as its first
              argument, filling in the array named as the second argument.  It
              clears  the  array  first.  Here too, the return value is one on
              success and zero upon failure.


ATTRIBUTES
       See attributes(7) for descriptions of the following attributes:


       box; cbp-1 | cbp-1 l | l .  ATTRIBUTE TYPE ATTRIBUTE VALUE = Availabil‐
       ity   text/gawk = Stability Volatile


NOTES
       The  array  created by reada() is identical to that written by writea()
       in the sense that the contents are the same. However, due to  implemen‐
       tation  issues,  the  array traversal order of the recreated array will
       likely be different from that of the original array.  As array  traver‐
       sal  order  in AWK is by default undefined, this is not (technically) a
       problem.  If you need to guarantee a particular  traversal  order,  use
       the array sorting features in gawk to do so.

       The file contains binary data.  All integral values are written in net‐
       work byte order.  However, double precision floating-point  values  are
       written  as  native  binary  data.  Thus, arrays containing only string
       data can theoretically be dumped on systems with  one  byte  order  and
       restored on systems with a different one, but this has not been tried.
