KLDSTAT(2)               DragonFly 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() function 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];
             char        pathname[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.

     pathname     The full path 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() function.
