Definition at line 78 of file lib/compat.c. Referenced by clean_flist(), log_formatted(), and map_ptr(). { bcopy((char *) src, (char *) dest, n); return dest; }

char* strpbrk (  const char *    s, const char *    accept )

Find the first ocurrence in s of any character in accept. Derived from glibc Definition at line 91 of file lib/compat.c. Referenced by make_exclude(). { while (*s != '\0') { const char *a = accept; while (*a != '\0') { if (*a++ == *s) return (char *)s; } ++s; } return NULL; }

size_t strlcpy (  char *    d, const char *    s, size_t    bufsize )

Like strncpy but does not 0 fill the buffer and always null terminates. Parameters: bufsize  is the size of the destination buffer. Returns: index of the terminating byte.

size_t strlcat (  char *    d, const char *    s, size_t    bufsize )

Like strncat() but does not 0 fill the buffer and always null terminates. Parameters: bufsize  length of the buffer, which should be one more than the maximum resulting string length.
