GETMNTINFO(3)						   BSD Library Functions Manual 					     GETMNTINFO(3)

NAME
     getmntinfo -- get information about mounted file systems

LIBRARY
     Standard C Library (libc, -lc)

SYNOPSIS
     #include <sys/types.h>
     #include <sys/statvfs.h>

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

DESCRIPTION
     The getmntinfo() function returns an array of statvfs structures describing each currently mounted file system (see statvfs(2)).

     The getmntinfo() function passes its flags parameter transparently to getvfsstat(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 getvfsstat(2) or malloc(3).

SEE ALSO
     getvfsstat(2), mount(2), statvfs(2), mount(8)

HISTORY
     The getmntinfo() function first appeared in 4.4BSD.  It was converted from using getfsstat(2) to getvfsstat(2) in NetBSD 3.0.

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 application.
