| 54 | .Sh NAME | ||
| 55 | .Nm SSL_free | ||
| 56 | .Nd free an allocated SSL structure | ||
| 57 | .Sh SYNOPSIS | ||
| 58 | .In openssl/ssl.h | ||
| 59 | .Ft void | ||
| 60 | .Fn SSL_free "SSL *ssl" | ||
| 61 | .Sh DESCRIPTION | ||
| 62 | .Fn SSL_free | ||
| 63 | decrements the reference count of | ||
| 64 | .Fa ssl , | ||
| 65 | and removes the | ||
| 66 | .Vt SSL | ||
| 67 | structure pointed to by | ||
| 68 | .Fa ssl | ||
| 69 | and frees up the allocated memory if the reference count has reached 0. | ||
| 70 | If | ||
| 71 | .Fa ssl | ||
| 72 | is a | ||
| 73 | .Dv NULL | ||
| 74 | pointer, no action occurs. | ||
| 75 | .Pp | ||
| 76 | .Fn SSL_free | ||
| 77 | also calls the | ||
| 78 | .Xr free 3 Ns | ||
| 79 | ing procedures for indirectly affected items, if applicable: the buffering | ||
| 80 | .Vt BIO , | ||
| 81 | the read and write | ||
| 82 | .Vt BIOs , | ||
| 83 | cipher lists specially created for this | ||
| 84 | .Fa ssl , | ||
| 85 | the | ||
| 86 | .Sy SSL_SESSION . | ||
| 87 | Do not explicitly free these indirectly freed up items before or after calling | ||
| 88 | .Fn SSL_free , | ||
| 89 | as trying to free things twice may lead to program failure. | ||
| 90 | .Pp | ||
| 91 | The | ||
| 92 | .Fa ssl | ||
| 93 | session has reference counts from two users: the | ||
| 94 | .Vt SSL | ||
| 95 | object, for which the reference count is removed by | ||
| 96 | .Fn SSL_free | ||
| 97 | and the internal session cache. | ||
| 98 | If the session is considered bad, because | ||
| 99 | .Xr SSL_shutdown 3 | ||
| 100 | was not called for the connection and | ||
| 101 | .Xr SSL_set_shutdown 3 | ||
| 102 | was not used to set the | ||
| 103 | .Vt SSL_SENT_SHUTDOWN | ||
| 104 | state, the session will also be removed from the session cache as required by | ||
| 105 | RFC 2246. | ||
