READFILE(3am)                       GNU Awk Extension Modules                       READFILE(3am)

       readfile - return the entire contents of a file as a string

       @load "readfile"

       result = readfile("/some/path")

       For making whole files be single records:

       @load "readfile"
       BEGIN { PROCINFO["readfile"] = 1 }

       The  readfile extension adds a single function named readfile().  The argument is the name
       of the file to read.  The return value is a string containing the entire contents  of  the
       requested file.

       Upon error, the function returns the empty string and sets ERRNO.

       In  addition,  it  adds  an input parser that is activated if PROCINFO["readfile"] exists.
       When activated, each input file is returned in its entirety as $0.  RT is set to the  null

       @load "readfile"
       contents = readfile("/path/to/file");
       if (contents == "" && ERRNO != "") {
           print("problem reading file", ERRNO) > "/dev/stderr"
