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

     getmntinfo - get information about mounted file systems

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

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

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

     The getmntinfo() function passes its flags parameter transparently to

     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 variable errno is
     set to indicate the error.  Although the pointer mntbufp will be unmodi-
     fied, any information previously returned by getmntinfo() will be lost.

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

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

     The getmntinfo() function first appeared in 4.4BSD.

     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(3)'d  by the applica-
