Detailed Description

Data streams control panel.

Manages data streams

Macro Definition Documentation

◆ SHAREDSHMDIR

#define SHAREDSHMDIR data.shmdir

default location of file mapped semaphores, can be over-ridden by env variable MILK_SHM_DIR

Function Documentation

◆ find_streams()

int find_streams	(	STREAMINFO *	streaminfo,
		int	filter,
		const char *	namefilter
	)

find shared memory streams on system

If filter is set to 1, require stream name to contain namefilter string streaminfo needs to be pre-allocated

◆ get_process_name_by_pid()

int get_process_name_by_pid	(	const int	pid,
		char *	pname
	)

INITIALIZE ncurses

◆ initncurses()

static int initncurses ( )

static

INITIALIZE ncurses

◆ streamCTRL_CTRLscreen()

errno_t streamCTRL_CTRLscreen ( )

Purpose

Control screen for stream structures

Description

Relies on ncurses for display

◆ streamCTRL_print_procpid()

static int streamCTRL_print_procpid	(	pid_t	procpid,
		pid_t *	upstreamproc,
		int	NBupstreamproc,
		uint32_t	mode
	)

static

print PID with highlighting
