NAME
     ggeettmmnnttiinnffoo - get information about mounted file systems

LLIIBBRRAARRYY
     Standard C Library (libc, -lc)

SYNOPSIS
     ##iinncclluuddee <>

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

DESCRIPTION
     The ggeettmmnnttiinnffoo() function returns an array of ssttaattffss() structures
     describing each currently mounted file system (see statfs(2)).

     The ggeettmmnnttiinnffoo() function passes its flags argument transparently to
     getfsstat(2).

RETURN VALUES
     On successful completion, ggeettmmnnttiinnffoo() 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 variable errno is
     set to indicate the error.  Although the pointer mntbufp will be unmodi-
     fied, any information previously returned by ggeettmmnnttiinnffoo() will be lost.

EERRRROORRSS
     The ggeettmmnnttiinnffoo() 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), mount(2), statfs(2), mount(8)

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

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

     The memory allocated by ggeettmmnnttiinnffoo() cannot be free(3)'d by the applica-
     tion.
