dpid.h(3) libdaemon dpid.h(3) 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 #define DAEMON_PID_FILE_KILL_WAIT_AVAILABLE 1 This variable is defined to 1 iff daemon_pid_file_kill_wait() is supported. Since: 0.3 See also: daemon_pid_file_kill_wait() Definition at line 82 of file dpid.h. Typedef Documentation typedef const char*(* daemon_pid_file_proc_t)(void) Prototype of a function for generating the name of a PID file. Definition at line 37 of file dpid.h. 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 Examples: testd.c. const char* daemon_pid_file_proc_default (void) A function for creating a pid file name from daemon_pid_file_ident. Returns: The PID file path 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. Author Generated automatically by Doxygen for libdaemon from the source code. Version 0.14 17 Jan 2010 dpid.h(3)
