void cleanup_subsystem_ycontrol ( status_t  res)

Cleanup the subsystem variables.

Parameters
resfinal status for trace message
Here is the caller graph for this function:

◆ connect_subsystem_srid()

status_t connect_subsystem_srid ( const char *  server_root,
int *  retfd 
)

Connect the subsystem for YControl using a server root.

Parameters
server_root
  • server root ID to use in multi-instance mode
  • NULL if single-instance mode
[out]retfdaddress of return file descriptor number
  • *retfd file descriptor number used for this connection
Returns
status

Here is the caller graph for this function:

◆ connect_subsystem_ycontrol()

status_t connect_subsystem_ycontrol ( int *  retfd)

Connect the subsystem for YControl.

Parameters
[out]retfdaddress of return file descriptor number
  • *retfd file descriptor number used for this connection
Returns
status
Here is the call graph for this function:

◆ init_subsystem_ycontrol()

status_t init_subsystem_ycontrol ( int  trace_level,
const char *  subsys_id 
)

@

Init the subsystem for use within a YControl subsystem

Internal API for YControl use only.

STDIN is input from the client (sent to YP server) STDOUT is output to the client (rcvd from YP server)

THIS FUNCTION WILL SET NON-BLOCKING IO FOR THE SOCKET DO NOT USE FOR yangcli-pro or yp-shell; FOR ycontrol only

Parameters
trace_leveldefault trace level to use if no -t CLI entered
subsys_idsubsystem identifier
Returns
status
Here is the call graph for this function:
Here is the caller graph for this function:

◆ init_subsystem_ycontrol_ha()

status_t init_subsystem_ycontrol_ha ( int  trace_level,
const char *  subsys_id,
const char *  server_id,
const char *  server_addr,
uint16  server_port 
)

@

Init the subsystem for use within a YControl subsystem

Internal API for YControl use only.

STDIN is input from the client (sent to YP server) STDOUT is output to the client (rcvd from YP server)

THIS FUNCTION WILL SET NON-BLOCKING IO FOR THE SOCKET DO NOT USE FOR yangcli-pro or yp-shell; FOR ycontrol only

Parameters
trace_leveldefault trace level to use if no -t CLI entered
subsys_idsubsystem identifier
server_idthe server ID to connect to
server_addrthe server address to connect to
server_portthe server port to connect to
Returns
status
Here is the caller graph for this function:

◆ run_subsystem()

int run_subsystem ( proto_id_t  protocol_id,
int  trace_level,
int  argc,
char **  argv 
)

Run the subsystem : entry point.

STDIN is input from the SSH client (sent to YP server)
STDOUT is output to the SSH client (rcvd from YP server)

Parameters
protocol_iddefault protocol to use if no -p CLI entered
trace_leveldefault trace level to use if no -t CLI entered
argcargument count passed to program
argvargument list passed to program
Returns
0 if NO_ERR
1 if error connecting or logging into ncxserver
Here is the call graph for this function:

◆ run_subsystem_ex()

int run_subsystem_ex ( proto_id_t  protocol_id,
int  trace_level,
int  argc,
char **  argv,
char **  envp,
subsys_stdin_fn_t  stdin_fn,
subsys_stdout_fn_t  stdout_fn,
int32  stdin_len 
)

Run the subsystem : entry point (extended)

STDIN is input from the SSH client (sent to YP server)
STDOUT is output to the SSH client (rcvd from YP server)

Parameters
protocol_iddefault protocol to use if no -p CLI entered
trace_leveldefault trace level to use if no -t CLI entered
argcargument count passed to program
argvargument list passed to program
envpenvironment list passed to program
stdin_fnfunction to call for reading a buffer from STDIN
NULL to use internal default function
stdout_fnfunction to call for writing a buffer to STDOUT
NULL to use internal default function
stdin_lencontent length if limited or known in advance
-1 if content_length not known or used
Returns
0 if NO_ERR
1 if error connecting or logging into ncxserver
Here is the call graph for this function:

◆ run_subsystem_full()

int run_subsystem_full ( proto_id_t  protocol_id,
int  trace_level,
int  argc,
char **  argv,
char **  envp,
subsys_stdin_fn_t  stdin_fn,
subsys_stdout_fn_t  stdout_fn,
int32  stdin_len 
)

Run the subsystem : entry point (full)

Appears to be a duplicate of run_subsystem_ex. STDIN is input from the SSH client (sent to YP server)
STDOUT is output to the SSH client (rcvd from YP server)
