From 9d26efa90c6dcbcd6b3e586c9927b6058ef4d529 Mon Sep 17 00:00:00 2001 From: Ulrich Drepper Date: Sat, 11 Apr 2009 05:34:20 +0000 Subject: * stdio-common/printf.h (struct printf_info): Add user element. New types printf_arginfo_size_function, printf_va_arg_function. Declare register_printf_specifier, register_printf_modifier, register_printf_type. * stdio-common/printf-parse.h (struct printf_spec): Add size element. (union printf_arg): Add pa_user element. Adjust __printf_arginfo_table type. Add __printf_va_arg_table, __printf_modifier_table, __handle_registered_modifier_mb, and __handle_registered_modifier_wc declarations. * stdio-common/printf-parsemb.c: Recognize registered modifiers. If registered arginfo call failed try normal specifier. * stdio-common/printf-prs.c: Pass additional parameter to arginfo function. * stdio-common/Makefile (routines): Add reg-modifier and reg-type. * stdio-common/Versions: Export register_printf_modifier, register_printf_type, and register_printf_specifier for GLIBC_2.10. * stdio-common/reg-modifier.c: New file. * stdio-common/reg-type.c: New file. * stdio-common/reg-printf.c (__register_printf_specifier): New function. Mostly the old __register_printf_function function but uses locking and type of third parameter changed. (__register_printf_function): Implement using __register_printf_specifier. * stdio-common/vfprintf.c (vfprintf): Collect argument sizes in calls to arginfo functions. Allocate enough memory for user-defined types. Call new va_arg functions to get user-defined types. Try installed handlers even for existing format specifiers first. --- stdio-common/Versions | 1 + 1 file changed, 1 insertion(+) (limited to 'stdio-common/Versions') diff --git a/stdio-common/Versions b/stdio-common/Versions index af693ff..3503a84 100644 --- a/stdio-common/Versions +++ b/stdio-common/Versions @@ -55,6 +55,7 @@ libc { } GLIBC_2.10 { psiginfo; + register_printf_modifier; register_printf_type; register_printf_specifier; } GLIBC_PRIVATE { # global variables -- cgit v1.1
