Subject: Introduce print_obj_by_addr_fn and sprint_obj_by_addr_fn
X-Git-Tag: v5.1~83
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=db9213bcd0199ee808ce86d2a033fcbcf6783513;p=strace

Introduce print_obj_by_addr_fn and sprint_obj_by_addr_fn

These types are going to be used in signatures of functions that take
print_*time* functions as parameters.

* defs.h (print_obj_by_addr_fn, sprint_obj_by_addr_fn): New types.
* desc.c (decode_select): Use them.
