dlog.h

NAME

dlog.h - Contains a robust API for logging messages.

SYNOPSIS

#include <syslog.h>
#include <stdarg.h>

Defines

#define DAEMON_GCC_PRINTF_ATTR(a, b)

#define DAEMON_LOGV_AVAILABLE 1
This variable is defined to 1 iff daemon_logv() is supported.

Enumerations

enum daemon_log_flags { DAEMON_LOG_SYSLOG = 1, DAEMON_LOG_STDERR = 2, DAEMON_LOG_STDOUT = 4, DAEMON_LOG_AUTO = 8 }
Specifies where to send the log messages to.

Functions

void daemon_log (int prio, const char *t,...) DAEMON_GCC_PRINTF_ATTR(2
Log a message using printf format strings using the specified syslog priority.
void daemon_logv (int prio, const char *t, va_list ap)
Same as daemon_log(), but without variadic arguments.
char * daemon_ident_from_argv0 (char *argv0)
Return a sensible syslog identification for daemon_log_ident generated from argv[0].

Variables

enum daemon_log_flags daemon_log_use
This variable is used to specify the log target(s) to use.
const char * daemon_log_ident
Specifies the syslog identification, use daemon_ident_from_argv0() to set this to a sensible value or generate your own.

Detailed Description

Contains a robust API for logging messages.

Definition in file dlog.h.

Define Documentation

#define DAEMON_GCC_PRINTF_ATTR(a, b)

Definition at line 58 of file dlog.h.

#define DAEMON_LOGV_AVAILABLE 1

This variable is defined to 1 iff daemon_logv() is supported.

Definition at line 68 of file dlog.h.

Enumeration Type Documentation

enum daemon_log_flags

Specifies where to send the log messages to.

The global variable daemon_log_use takes values of this type.

Enumerator:

DAEMON_LOG_SYSLOG

Log messages are written to syslog.

DAEMON_LOG_STDERR

Log messages are written to STDERR.

DAEMON_LOG_STDOUT

Log messages are written to STDOUT.

DAEMON_LOG_AUTO

If this is set a daemon_fork() will change this to DAEMON_LOG_SYSLOG in the daemon process.

Definition at line 38 of file dlog.h.

Function Documentation

char* daemon_ident_from_argv0 (char * argv0)

Return a sensible syslog identification for daemon_log_ident generated from argv[0].

This will return a pointer to the file name of argv[0], i.e. strrchr(argv[0], '\')+1

Parameters:

argv0 argv[0] as passed to main()

Returns:

The identification string

Examples: testd.c.

void daemon_log (int prio, const char * t, ...)

Log a message using printf format strings using the specified syslog priority.

Parameters:

prio The syslog priority (PRIO_xxx constants)
t,... The text message to log

Examples: testd.c.

void daemon_logv (int prio, const char * t, va_list ap)

Same as daemon_log(), but without variadic arguments.

Since:

0.11

See also:

DAEMON_LOGV_AVAILABLE

Variable Documentation

const char* daemon_log_ident

Specifies the syslog identification, use daemon_ident_from_argv0() to set this to a sensible value or generate your own.

Examples: testd.c.

enum daemon_log_flags daemon_log_use

This variable is used to specify the log target(s) to use.

Defaults to DAEMON_LOG_STDERR|DAEMON_LOG_AUTO
