    GETMNTINFO(3)	    UNIX Programmer's Manual	    GETMNTINFO(3)

    NAME
         getmntinfo - get information about mounted file systems

    SYNOPSIS
         #include <sys/param.h>
         #include <sys/mount.h>

         int
         getmntinfo(mntbufp,flags)
         struct statfs **mntbufp;
         int flags

    DESCRIPTION
         The getmntinfo() function returns an array of statfs struc-
         tures describing each currently mounted file system (see
         statfs(2).

         The getmntinfo() function passes its flags parameter tran-
         sparently to getfsstat(2).

    RETURN VALUES
         On successful completion, getmntinfo() returns a count of
         the number of elements in the array.  The pointer to the
         array is stored into mntbufp.

         If an error occurs, zero is returned and the external vari-
         able errno is set to indicate the error.  Although the
         pointer mntbufp will be unmodified, any information previ-
         ously returned by getmntinfo() will be lost.

    ERRORS
         The getmntinfo() function may fail and set errno for any of
         the errors specified for the library routines getfsstat(2)
         or malloc(3).

    SEE ALSO
         getfsstat(2), statfs(2), mount(2), mount(8)

    HISTORY
         The getmntinfo() function first appeared in 4.4BSD.

    BUGS
         The getmntinfo() function writes the array of structures to
         an internal static object and returns a pointer to that
         object. Subsequent calls to getmntinfo() will modify the
         same object.

         The memory allocated by getmntinfo() cannot be free(2)'d by
         the application.
