For a detailed description, refer to documents for the respective single-byte counterpart, such as memchr(3). SEE ALSO memchr(3), memcmp(3), memcpy(3), memmove(3), memset(3), stpcpy(3), stpncpy(3), strcasecmp(3), strcat(3), strchr(3), strcmp(3), strcpy(3), strcspn(3), strdup(3), strlcat(3), strlcpy(3), strlen(3), strncat(3), strncmp(3), strncpy(3), strnlen(3), strpbrk(3), strrchr(3), strspn(3), strstr(3) STANDARDS These functions conform to ISO/IEC 9899:1999 ("ISO C99"), with the exception of wcpcpy(), wcpncpy(), wcscasecmp(), wcsdup(), wcsncasecmp(), and wcsnlen(), which conform to IEEE Std 1003.1-2008 ("POSIX.1"); and wcslcat(), wcslcpy(), and wmempcpy(), which are extensions.
