| 65 | * BIO_snprintf and BIO_vsnprintf return -1 for overflow, | ||
| 66 | * due to the history of this API. Justification: | ||
| 67 | * | ||
| 68 | * Traditional snprintf surfaced in 4.4BSD, and returned | ||
| 69 | * "number of bytes wanted". Solaris and Windows opted to | ||
| 70 | * return -1. A draft standard was written which returned -1. | ||
| 71 | * Due to the large volume of code already using the first | ||
| 72 | * semantics, the draft was repaired before standardization to | ||
| 73 | * specify "number of bytes wanted" plus "-1 for character conversion | ||
| 74 | * style errors". Solaris adapted to this rule, but Windows stuck | ||
| 75 | * with -1. | ||
| 76 | * | ||
| 77 | * Original OpenSSL comment which is full of lies: | ||
| 78 | * | ||
| 79 | * "In case of truncation, return -1 like traditional snprintf. | ||
| 80 | * (Current drafts for ISO/IEC 9899 say snprintf should return | ||
| 81 | * the number of characters that would have been written, | ||
| 82 | * had the buffer been large enough.)" | ||
