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 re

ferred to by
fileid into stat.

struct kld_file_stat {

int version; /* set to sizeof(link

er_file_stat) */
char name[MAXPATHLEN];
int refs;
int id;
caddr_t address; /* load address */
size_t size; /* size in bytes */

};

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.

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) func

tion.
