0021 DESCRIPTION
0022 -----------
0023 When process is about to copy it self (i.e. perform forking in UNIX terms),
0024 Enduro/X requires certain tasks to be performed before this action. Particularly,
0025 if System V IPC transport is used by Enduro/X, then auxiliary threads shall be
0026 terminated and contexts released. Thus if doing manual *fork()*, then before this
0027 call, parent shall call *ndrx_atfork_prepare()* procedure. Procedure can
0028 be registered with *pthread_atfork()*, passing it to 'prepare' argument.
0029
0030 At given time function does some logic by System V IPC, for other IPC
0031 no logic is executed. But this fact is subject of change, and in future releases
0032 some other tasks might be required to be one by Enduro/X before process forking,
0033 thus it is recommended to use *ndrx_fork()*, call manually
0034 *ndrx_atfork_prepare()* or register it with *pthread_atfork()*
