The ANSI_SYNOPSIS in memset.c says (at least for 1.16.0): void *memset(const void *<[dst]>, int <[c]>, size_t <[length]>); The const for dst is in error. This error is (obviously) only in the comment and the man page. The line should read void *memset(void *<[dst]>, int <[c]>, size_t <[length]>); Craig Howland
