Revision 1.13, Tue Jun 6 05:06:25 2000 UTC (20 years, 4 months ago) by jhawk
Branch: MAIN
CVS Tags: netbsd-1-5-base, netbsd-1-5-RELEASE, netbsd-1-5-PATCH003, netbsd-1-5-PATCH002, netbsd-1-5-PATCH001, netbsd-1-5-BETA2, netbsd-1-5-BETA, netbsd-1-5-ALPHA2, netbsd-1-5
Changes since 1.12: +2 -3 lines

Stop using DDB-specific "%n" kprintf() format specifier. This was
important as db_sym() can be called through printf() rather than
db_printf(), causing a trap as the standard %n usage is invoked.

The DDB-specific %n code should disappear from subr_prf.c soon...
