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.

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.
