-/* This is the default routine to handle BFD error messages.
- Like fprintf (stderr, ...), but also handles some extra format specifiers.
-
- %A section name from section. For group components, print group name too.
- %B file name from bfd. For archive components, prints archive too.
-
- Note - because these two extra format specifiers require special handling
- they are scanned for and processed in this function, before calling
- vfprintf. This means that the *arguments* for these format specifiers
- must be the first ones in the variable argument list, regardless of where
- the specifiers appear in the format string. Thus for example calling
- this function with a format string of:
-
- "blah %s blah %A blah %d blah %B"
+/* This macro and _doprnt taken from libiberty _doprnt.c, tidied a
+ little and extended to handle '%A' and '%B'. */
- would involve passing the arguments as:
+#define PRINT_TYPE(TYPE) \
+ do \
+ { \
+ TYPE value = va_arg (ap, TYPE); \
+ result = fprintf (stream, specifier, value); \
+ } while (0)
- "blah %s blah %A blah %d blah %B",
- asection_for_the_%A,
- bfd_for_the_%B,
- string_for_the_%s,
- integer_for_the_%d);
