#---------------------------------------------------------------------- # # mark_pgdllimport.pl # Perl script that tries to add PGDLLIMPORT markings to PostgreSQL # header files. # # This relies on a few idiosyncrasies of the PostgreSQL coding style, # such as the fact that we always use "extern" in function # declarations, and that we don't use // comments. It's not very # smart and may not catch all cases. # # It's probably a good idea to run pgindent on any files that this # script modifies before committing. This script uses as arguments # a list of the header files to scan for the markings. # # Portions Copyright (c) 1996-2025, PostgreSQL Global Development Group # Portions Copyright (c) 1994, Regents of the University of California # # src/tools/mark_pgdllimport.pl # #----------------------------------------------------------------------
