This name will be used in error messages generated by sd-event3 for this source. Specified name must point to a NUL-terminated string or be NULL. In the latter case, the name will be unset. The string is copied internally, so the name argument is not referenced after the function returns. sd_event_set_name() can be used to query the current name assigned to source source. It returns a pointer to the current name (possibly NULL) in name. On success, sd_event_set_name() and sd_event_get_name() return a non-negative integer. On failure, they return a negative errno-style error code. Returned errors may indicate the following problems: -EINVAL source is not a valid pointer to an sd_event_source structure or the name argument for sd_event_get_name() is NULL. -ENOMEM Not enough memory to copy the name. Functions described here are available as a shared library, which can be compiled and linked to with the libsystemd pkg-config1 file. sd-event3, sd_event_add_time3, sd_event_add_child3, sd_event_add_signal3, sd_event_add_defer3, sd_event_run3
