Power I/O function handler

Updated: April 19, 2023

Prototype:

int (*power) ( resmgr_context_t * ctp,
               io_power_t * msg,
               RESMGR_OCB_T * ocb )
This function is reserved by BlackBerry QNX for future use. You should initialize the I/O table using iofunc_func_init() and not modify this entry.
