modstat(2)
MODSTAT(2) BSD System Calls Manual MODSTAT(2)
NAME
modstat — get status of kernel module
LIBRARY
Standard C Library (libc, -lc)
SYNOPSIS
#include <sys/param.h>
#include <sys/module.h>
int
modstat(int modid, struct module_stat *stat);
DESCRIPTION
The modstat() system call writes the info for the kernel module referred
to by modid into stat.
struct module_stat {
int version; /* set to sizeof(module_stat) */
char name[MAXMODNAME];
int refs;
int id;
modspecific_t data;
};
typedef union modspecific {
int intval;
u_int uintval;
long longval;
u_long ulongval;
} modspecific_t;
version This field is set to the size of the structure mentioned
above by the code calling modstat(), and not modstat()
itself.
name The name of the module referred to by modid.
refs The number of modules referenced by modid.
id The id of the module specified in modid.
data Module specific data.
RETURN VALUES
The modstat() 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 module referred to by modid is filled into the
structure pointed to by stat unless:
[ENOENT] The module 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.
