# Suppress a valgrind message about use of uninitialized memory in memchr(). # POSIX states that when the character is found, memchr must not read extra # bytes in an overestimated length (for example, where memchr is used to # implement strnlen). However, we use a safe word read to provide a speedup. { memchr-value4 Memcheck:Value4 fun:rpl_memchr } { memchr-value8 Memcheck:Value8 fun:rpl_memchr }
