SYSCALL_MODULE(9)

SYSCALL_MODULE(9)        BSD Kernel Developer's Manual       SYSCALL_MODULE(9)

NAME
     SYSCALL_MODULE — syscall kernel module declaration macro

SYNOPSIS
     #include <sys/param.h>
     #include <sys/kernel.h>
     #include <sys/proc.h>
     #include <sys/module.h>
     #include <sys/sysent.h>

     SYSCALL_MODULE(name, int *offset, struct sysent *new_sysent,
         modeventhand_t evh, void *arg);

DESCRIPTION
     The SYSCALL_MODULE() macro declares a new syscall.  SYSCALL_MODULE()
     expands into a kernel module declaration with name ‘sys/name’.

     The rest of the arguments expected by this macro are:

     offset      A pointer to an int which saves the offset in struct sysent
                 where the syscall is allocated.  If the location pointed to
                 by offset holds a non 0 number it will be used if possible.
                 If it holds 0 then one will be assigned.

     new_sysent  is a pointer to a structure that specifies the function
                 implementing the syscall and the number of arguments this
                 function needs (see <sys/sysent.h>).

     evh         A pointer to the kernel module event handler function with
                 the argument arg.  Please refer to module(9) for more infor‐
                 mation.

     arg         The argument passed to the callback functions of the evh
                 event handler when it is called.

     The syscall number assigned to the module can be retrieved using the
     modstat(3) and modfind(3) library functions in libc.  The MACRO
     SYSCALL_MODULE_HELPER() includes SYSCALL_MODULE() and much of its boiler‐
     plate code.

EXAMPLES
     A minimal example for a syscall module can be found in
     /usr/share/examples/kld/syscall/module/syscall.c.
