In general, the 38.Sy libproc 39library takes care of managing the need to call this function; 40however, debuggers, introspection tools, and others that are 41interposing on rtld activity may need to call this function. Note that 42the 43.Fn Pupdate_syms 44function is only meaningful for active processes. It will do nothing on 45process handles that refer to core files, zombie processes, and ELF 46objects. 47.Sh INTERFACE STABILITY 48.Sy Uncommitted 49.Sh MT-LEVEL 50See 51.Sy LOCKING 52in 53.Xr libproc 3LIB . 54.Sh SEE ALSO 55.Xr libproc 3LIB , 56.Xr Pupdate_maps 3PROC 57
