KLDSTAT(2)		      System Calls Manual		    KLDSTAT(2)

NAME
       kldstat -- get status of	kld file

LIBRARY
       Standard	C Library (libc, -lc)

SYNOPSIS
       #include	<sys/param.h>
       #include	<sys/linker.h>

       int
       kldstat(int fileid, struct kld_file_stat	*stat);

DESCRIPTION
       The  kldstat()  system call writes the info for the file	referred to by
       fileid into stat.

       struct kld_file_stat {
	       int	   version;    /* set to sizeof(struct kld_file_stat) */
	       char	   name[MAXPATHLEN];
	       int	   refs;
	       int	   id;
	       caddr_t	   address;
	       size_t	   size;
	       char	   pathname[MAXPATHLEN];
       };

       version	   This	field is set to	the size of  the  structure  mentioned
		   above  by the code calling kldstat(), and not kldstat() it-
		   self.

       name	   The name of the file	referred to by fileid.

       refs	   The number of modules referenced by fileid.

       id	   The id of the file specified	in fileid.

       address	   The load address of the kld file.

       size	   The amount of memory	in bytes allocated by the file.

       pathname	   The full name of the	file referred to by fileid,  including
		   the path.

RETURN VALUES
       The kldstat() function returns the value	0 if successful; otherwise the
       value  -1  is returned and the global variable errno is set to indicate
       the error.

ERRORS
       The information for the file referred to	by fileid is filled  into  the
       structure pointed to by stat unless:

       [ENOENT]		  The file was not found (probably not loaded).

       [EINVAL]		  The  version	specified in the version field of stat
			  is not the proper version.  You would	 need  to  re-
			  build	 world,	 the  kernel,  or your application, if
			  this error occurs, given that	you did	properly  fill
			  in the version field.

       [EFAULT]		  There	was a problem copying one, some, or all	of the
			  fields into stat in the copyout(9) function.

HISTORY
       The kld interface first appeared	in FreeBSD 3.0.

BUGS
       The pathname may	not be accurate	if the file system mounts have changed
       since the module	was loaded, or if this function	is called within a ch-
       rooted environment.
