In general, the +.Sy libproc +library takes care of managing the need to call this function; however, +debuggers, introspection tools, and others that are interposing on rtld +activity or other actions, may need to call this function. +Note that the +.Fn Pupdate_maps +function is only meaningful for active processes. It will do nothing on +process handles that refer to core files, zombie processes, and ELF +objects. +.Sh INTERFACE STABILITY +.Sy Uncommitted +.Sh MT-LEVEL +See +.Sy LOCKING +in +.Xr libproc 3LIB . +.Sh SEE ALSO +.Xr libproc 3LIB , +.Xr Pupdate_syms 3PROC |
