NAME
dpid.h -
Contains an API for manipulating PID files.
SYNOPSIS
#include <sys/types.h>
Defines
#define DAEMON_PID_FILE_KILL_WAIT_AVAILABLE 1
This variable is defined to 1 iff daemon_pid_file_kill_wait() is supported.
Typedefs
typedef const char *(* daemon_pid_file_proc_t )(void)
Prototype of a function for generating the name of a PID file.
Functions
const char * daemon_pid_file_proc_default (void)
A function for creating a pid file name from daemon_pid_file_ident.
int daemon_pid_file_create (void)
Creates PID pid file for the current process.
int daemon_pid_file_remove (void)
Removes the PID file of the current process.
pid_t daemon_pid_file_is_running (void)
Returns the PID file of a running daemon, if available.
int daemon_pid_file_kill (int s)
Kills a running daemon, if available.
int daemon_pid_file_kill_wait (int s, int m)
Similar to daemon_pid_file_kill() but waits until the process died.
Variables
const char * daemon_pid_file_ident
Identification string for the PID file name, only used when daemon_pid_file_proc is set to daemon_pid_file_proc_default().
daemon_pid_file_proc_t daemon_pid_file_proc
A function pointer which is used to generate the name of the PID file to manipulate.
Detailed Description
Contains an API for manipulating PID files.
Definition in file dpid.h.
Define Documentation

Function Documentation
int daemon_pid_file_create (void)
Creates PID pid file for the current process. Returns:
zero on success, nonzero on failure
Examples:
testd.c.
pid_t daemon_pid_file_is_running (void)
Returns the PID file of a running daemon, if available. Returns:
The PID or negative on failure
Examples:
testd.c.
int daemon_pid_file_kill (int s)
Kills a running daemon, if available. Parameters:
s The signal to send
Returns:
zero on success, nonzero on failure
int daemon_pid_file_kill_wait (int s, int m)
Similar to daemon_pid_file_kill() but waits until the process died. This functions is new in libdaemon 0.3. The macro
DAEMON_PID_FILE_KILL_WAIT_AVAILABLE is defined iff libdaemon supports this function.
Parameters:
s The signal to send
m Seconds to wait at maximum
Returns:
zero on success, nonzero on failure (timeout condition is considered a failure)
Since:
0.3
See also:
DAEMON_PID_FILE_KILL_WAIT_AVAILABLE

int daemon_pid_file_remove (void)
Removes the PID file of the current process. Returns:
zero on success, nonzero on failure
Examples:
testd.c.
Variable Documentation
const char* daemon_pid_file_ident
Identification string for the PID file name, only used when daemon_pid_file_proc is set to daemon_pid_file_proc_default(). Use
daemon_ident_from_argv0() to generate an identification string from argv[0]
Examples:
testd.c.
daemon_pid_file_proc_t daemon_pid_file_proc
A function pointer which is used to generate the name of the PID file to manipulate. Points to daemon_pid_file_proc_default() by default.
