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 named as 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.
new_sysent is a pointer to a structure that specifies the function
implementing the syscall and the number of arguments this
function needs (see
evh A pointer to the kernel module event handler function with
the argument arg. Please refer to module(9) for more
information.
arg The argument passed to the callback functions of the evh
event handler when it is called.
