Crate libpam_sys

Expand description

libpam-sys provides low-level access to LibPAM.

Everything in here is directly as exported from the LibPAM library or its header files, with two exceptions:

The pam_impl submodule (and the associated pam_impl_name! macro), which can be used to detect the current PAM implementation.
The aliases submodule, which contains convenient aliases for callback types used in libpam, so you don’t have to type unsafe extern "C" fn(this is so long) all the time.

This documentation was built for the LinuxPam implementation.

You can override this at build time by setting the LIBPAMSYS_IMPL environment variable to one of the values of the pam_impl::PamImpl enum. For more information about configuration, see the documentation of libpam-sys-impls.

Re-exports§

pub use pam_modutil_redirect_fd::*;

Modules§

aliases: Convenience aliases for complex types in PAM.
pam_impl: Information about the current PAM implementation (or the implementation that is being built for).

Macros§

pam_impl_name: The name of the PAM implementation this library was built against, as a string.

Structs§

pam_conv: Used by PAM to communicate between the module and the application.
pam_handle: An opaque structure that PAM uses to communicate.
pam_message: A message sent into a PAM conversation.
pam_modutil_privs
pam_response: A response returned from a PAM conversation.
pam_xauth_data: Definition of the PAM_XAUTHDATA item. Compatible with xcb_auth_info_t.
