create_module (2) - Linux Man Pages
create_module: create a loadable module entry
NAMEcreate_module - create a loadable module entry
#include <linux/module.h> caddr_t create_module(const char *name, size_t size);
DESCRIPTIONNote: This system call is present only in kernels before Linux 2.6.
RETURN VALUEOn success, returns the kernel address at which the module will reside. On error, -1 is returned and errno is set appropriately.
- A module by that name already exists.
- name is outside the program's accessible address space.
- The requested size is too small even for the module header information.
- The kernel could not allocate a contiguous block of memory large enough for the module.
- create_module() is not supported in this version of the kernel (e.g., the kernel is version 2.6 or later).
- The caller was not privileged (did not have the CAP_SYS_MODULE capability).
VERSIONSThis system call is present on Linux only up until kernel 2.4; it was removed in Linux 2.6.
CONFORMING TOcreate_module() is Linux-specific.
NOTESThis obsolete system call is not supported by glibc. No declaration is provided in glibc headers, but, through a quirk of history, glibc versions before 2.23 did export an ABI for this system call. Therefore, in order to employ this system call, it was sufficient to manually declare the interface in your code; alternatively, you could invoke the system call using syscall(2).
