GETMNTINFO(3)						     Library Functions 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 structures describing each currently mounted file system (see statfs(2).

       The getmntinfo() function passes its flags parameter transparently 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 variable errno is set to indicate the error.  Although the pointer  mntbufp  will	be
       unmodified, any information previously 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.
