# NAME

`openpam_log` — log a message through syslog

# SYNOPSIS

`#include <sys/types.h>`
`#include <security/pam_appl.h>`
`#include <security/openpam.h>`

void
`openpam_log`(int level, const char *fmt, ...);

# DESCRIPTION

The `openpam_log`() function logs messages using syslog(3). It is primarily intended for internal use by the library and modules.

The level argument indicates the importance of the message. The following levels are defined:

`PAM_LOG_LIBDEBUG`
  Debugging messages. For internal use only.
`PAM_LOG_DEBUG`
  Debugging messages. These messages are normally not logged unless the global integer variable openpam_debug is set to a non-zero value, in which case they are logged with a syslog(3) priority of `LOG_DEBUG`.
`PAM_LOG_VERBOSE`
  Information about the progress of the authentication process, or other non-essential messages. These messages are logged with a syslog(3) priority of `LOG_INFO`.
`PAM_LOG_NOTICE`
  Messages relating to non-fatal errors. These messages are logged with a syslog(3) priority of `LOG_NOTICE`.
`PAM_LOG_ERROR`
  Messages relating to serious errors. These messages are logged with a syslog(3) priority of `LOG_ERR`.

The remaining arguments are a printf(3) format string and the corresponding arguments.

The `openpam_log`() function does not modify the value of errno.
