Name
ndrx_atfork_child — Function to be executed by child process after the fork if ndrx_fork() is not used
Synopsis
#include <atmi.h>
void ndrx_atfork_child(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 copied by fork() system call, ndrx_atfork_child() shall be executed by child process after the fork call. This ensures that Enduro/X sub-systems for child process cleans up any open resources. Particularly if fork is done by XATMI server then function deallocates any server resources open. NOTE that if any thread is doing XATMI client tasks, then tpterm(3) shall be called prior fork() is executed.
The logic of function is subject of change and in future releases some other tasks might be required to be done by Enduro/X after process forking, thus it is recommended to use ndrx_fork(), call manually ndrx_atfork_child() or register it with pthread_atfork()
