DDEESSCCRRIIPPTTIIOONN
     The ggeettmmnnttiinnffoo() function returns an array of statfs structures describ-
     ing each currently mounted file system (see statfs(2)).

     The ggeettmmnnttiinnffoo() function passes its _f_l_a_g_s parameter transparently to
     getfsstat(2).

RREETTUURRNN VVAALLUUEESS
     On successful completion, ggeettmmnnttiinnffoo() returns a count of the number of
     elements in the array.  The pointer to the array is stored into _m_n_t_b_u_f_p.

     If an error occurs, zero is returned and the external variable _e_r_r_n_o is
     set to indicate the error.  Although the pointer _m_n_t_b_u_f_p 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).

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

BBUUGGSS
     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(2)'d  by the applica-
     tion.
