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 ker-
                        nel, 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

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.
