B<len> at B<s> into a B<BIGNUM> and places it in B<ret>. If B<ret> is
NULL, a new B<BIGNUM> is created.
-BN_bn2lebinpad() and BN_bin2lbn() are identical to BN_bn2binpad() and
+BN_bn2lebinpad() and BN_lebin2bn() are identical to BN_bn2binpad() and
BN_bin2bn() except the buffer is in little-endian format.
BN_bn2hex() and BN_bn2dec() return printable strings containing the
buffer is too small.
BN_bn2hex() and BN_bn2dec() return a null-terminated string, or NULL
-on error. BN_hex2bn() and BN_dec2bn() return the the length of valid
-representation in hexadecimal or decimal digits, and 0 on error, in which
+on error. BN_hex2bn() and BN_dec2bn() return the number of characters
+used in parsing, or 0 on error, in which
case no new B<BIGNUM> will be created.
BN_print_fp() and BN_print() return 1 on success, 0 on write errors.
