 NAME
      exportent(), getexportent(), setexportent(), addexportent(),
      remexportent(), endexportent(), getexportopt() - access exported file
      system information

 SYNOPSIS
      #include <stdio.h>
      #include <exportent.h>

      FILE *setexportent();

      struct exportent *getexportent(FILE *fildep);

      int addexportent(FILE *filep, char *dirname, char *options);

      int remexportent(FILE *filep, char *dirname);

      char *getexportopt(struct exportent *xent, char *opt);

      void endexportent(FILE *filep);

 DESCRIPTION
      These routines access the exported filesystem information in
      /etc/xtab.

      setexportent()
                Open the export information file and return a file pointer
                to use with getexportent(), addexportent(), remexportent(),
                and endexportent().  Returns NULL if the file is locked or
                if an error is encountered in opening the file.

      getexportent()
                Read the next line from filep and return a pointer to an
                object with the following structure containing the broken-
                out fields of a line in file /etc/xtab.  The fields have
                meanings described in exports(4).

                #define ACCESS_OPT "access" /* machines that can mount fs */
                #define ROOT_OPT   "root"   /* machines with root access to fs */
                #define RO_OPT     "ro"     /* export read-only */
                #define ANON_OPT   "anon"   /* uid for anonymous requests */
                #define ASYNC_OPT  "async" /* all mounts will be aynchronous */

                struct exportent {
                       char *xent_dirname; /* directory (or file) to export */
                       char *xent_options; /* options, as above */
                       };

                getexportent() returns NULL if it encounters end of file.

      addexportent()
                Add the exportent to the end of the open file filep.  It
                returns 0 if successful and -1 on failure.

      remexportent()
                Remove the indicated entry from the list.  Returns 0 on
                success and -1 on failure.

      getexportopt()
                Scans the xent_options field of the exportent structure for
                a substring that matches opt.  Returns the string value of
                opt, or NULL if the option is not found.

      endexportent()
                Close the file.

 RETURN VALUE
      setexportent(), getexportent(), and getexportopt() return a NULL
      pointer on EOF or error.

      addexportent() and remexportent() return -1 if they fail.

 WARNINGS
      The returned exportent structure points to static information that is
      overwritten in each call.
