PAM_SYSLOG(3) Linux-PAM Manual PAM_SYSLOG(3)

pam_syslog, pam_vsyslog - send messages to the system logger

#include <syslog.h>

#include <security/pam_ext.h>

void pam_syslog(const pam_handle_t *pamh, int priority, const char *fmt, ...);

void pam_vsyslog(const pam_handle_t *pamh, int priority, const char *fmt, va_list args);

The pam_syslog function logs messages using syslog(3) and is intended for internal use by Linux-PAM and PAM service modules. The priority argument is formed by ORing the facility and the level values as documented in the syslog(3) manual page.

The pam_vsyslog function performs the same task as pam_syslog() with the difference that it takes a set of arguments which have been obtained using the stdarg(3) variable argument list macros.

pam(7)

The pam_syslog and pam_vsyslog functions are Linux-PAM extensions.
