KLDSTAT(2)		    BSD 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(linker_file_stat) */
	     char	 name[MAXPATHLEN];
	     int	 refs;
	     int	 id;
	     caddr_t	 address;	 /* load address */
	     size_t	 size;		 /* size in bytes */
	     char	 pathname[MAXPATHLEN];
     };

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

     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 size of 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 rebuild
			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.

     kldstat(8)

HISTORY
     The kld interface first appeared in FreeBSD 3.0.

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