NAME

ndrx_atfork_prepare − Function to be called before fork, if not using ndrx_fork(3)

SYNOPSIS

#include <atmi.h>

void ndrx_atfork_prepare(void);

For XATMI client link with −latmiclt −latmi −lubf −lnstd −lpthread −lrt −lm

For XATMI server link with −latmisrv|−latmisrvnomain|−latmisrvinteg −latmi −lubf −lnstd −lpthread −lrt −lm

DESCRIPTION

When process is about to copy it self (i.e. perform forking in UNIX terms), Enduro/X requires certain tasks to be performed before this action. Particularly, if System V IPC transport is used by Enduro/X, then auxiliary threads shall be terminated and contexts released. Thus if doing manual fork(), then before this call, parent shall call ndrx_atfork_prepare() procedure. Procedure can be registered with pthread_atfork(), passing it to prepare argument.

At given time function does some logic by System V IPC, for other IPC no logic is executed. But this fact is subject of change, and in future releases some other tasks might be required to be one by Enduro/X before process forking, thus it is recommended to use ndrx_fork(), call manually ndrx_atfork_prepare() or register it with pthread_atfork()
