SYNOPSIS

#include <flux/shell.h>

int flux_shell_service_register (flux_shell_t *shell,
                                 const char *method,
                                 flux_msg_handler_f cb,
                                 void *arg);

Link with -lflux-core.

DESCRIPTION

The job shell registers a unique service name with the flux broker on startup, and posts the topic string for this service in the context of the shell.init event. flux_shell_service_register() allows registration of a request handler cb for subtopic method on this service endpoint, allowing other job shells and/or flux commands to interact with arbitrary services within a job.

RETURN VALUE

Returns -1 on failure, 0 on success.

ERRORS

EINVAL: shell, method or cb is NULL.
