GETMNTINFO(3)	       FreeBSD Library Functions Manual		 GETMNTINFO(3)

NAME
     getmntinfo	-- get information about mounted file systems

LIBRARY
     Standard C	Library	(libc, -lc)

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

     int
     getmntinfo(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	argument 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 unmodi-
     fied, 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), mount(2), statfs(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(3)'d by the applica-
     tion.
