NAME
     delmntent - remove entry from mounted filesystem description file

SYNOPSIS
     #include <mntent.h>

     int delmntent(char *filep, struct mntent *mnt);

DESCRIPTION
     This routine removes entries from the mounted file system description
     file /etc/mtab.  The filep argument is the description file, usually
     /etc/mtab.	 The mnt argument is a pointer to an object with the following
     structure containing the broken-out fields of a line in the filesystem
     description file, <mntent.h>.  The fields have meanings described in
     fstab(4).

	  struct mntent {
	       char *mnt_fsname;   /* file system name */
	       char *mnt_dir; /* file system path prefix */
	       char *mnt_type;	   /* dbg, efs, nfs */
	       char *mnt_opts;	   /* ro, hide, etc. */
	       int  mnt_freq; /* dump frequency, in days */
	       int  mnt_passno;	   /* pass number on parallel fsck */
	  };

     Any combination of the fields mnt_fsname, mnt_dir, mnt_type, and mnt_opts
     may be specified in mnt to describe the entry to be removed.  If a field
     is non-NULL, the value given must match exactly to select this entry for
     removal.  Only the first entry which matches all non-NULL fields is
     removed.  The return value is 1 if an entry is removed, 0 if no match is
     found, and -1 if an error occurs.

FILES
     /etc/mtab
