man pam_start (Fonctions bibliothèques) - activating Linux-PAM
NAME
pam_start, pam_end - activating Linux-PAM
SYNOPSIS
#include <security/pam_appl.h> int pam_start(const char *service, const char *user, const struct pam_conv *conv, pam_handle_t **pamh_p); int pam_end(pam_handle_t *pamh, int pam_status);
DESCRIPTION
- pam_start
- Initialize the Linux-PAM library. Identifying the application with a particular service name. The username can take the value NULL, if not known at the time the interface is initialized. The conversation structure is passed to the library via the conv argument. (For a complete description of this and other structures the reader is directed to the more verbose Linux-PAM application developers' guide). Upon successful initialization, an opaque pointer-handle for future access to the library is returned through the contents of the pamh_p pointer.
- pam_end
- Terminate the Linux-PAM library. The service application associated with the pamh handle, is terminated. The argument, pam_status, passes the value most recently returned to the application from the library; it indicates the manner in which the library should be shutdown. Besides carrying a return value, this argument may be logically OR'd with PAM_DATA_SILENT to indicate that the module should not treat the call too seriously. It is generally used to indicate that the current closing of the library is in a fork(2)ed process, and that the parent will take care of cleaning up things that exist outside of the current process space (files etc.).
RETURN VALUE
- pam_start
- pam_end
- On success, PAM_SUCCESS is returned
ERRORS
May be translated to text with pam_strerror(3).
CONFORMING TO
