[PATCH 3/3 v2] src/readelf.c: Add support for print_debug_* output buffering
Aaron Merey
amerey@redhat.com
Thu May 22 22:28:54 GMT 2025
Safely handle stdout output during concurrent calls to print_debug_*
functions.
For any print_debug_* function and any function that could be called
from print_debug_* which also prints to stdout: add a FILE * argument
and replace all printf, puts, putchar with fprintf. All printing
to stdout will now be written to this FILE instead.
The FILE * is an interface to a per-thread dynamically-sized buffer.
libthread.a manages the allocation, printing and deallocation of
these buffers.
Signed-off-by: Aaron Merey <amerey@redhat.com>

v2:
Minor change to print_dwarf_addr declaration so patch applies cleanly
to main branch.
