3 | =head1 NAME | |
4 | ||
5 | OPENSSL_CTX, OPENSSL_CTX_new, OPENSSL_CTX_free - OpenSSL library context | |
6 | ||
7 | =head1 SYNOPSIS | |
8 | ||
9 | #include <openssl/crypto.h> | |
10 | ||
11 | typedef struct openssl_ctx_st OPENSSL_CTX; | |
12 | ||
13 | OPENSSL_CTX *OPENSSL_CTX_new(void); | |
14 | void OPENSSL_CTX_free(OPENSSL_CTX *ctx); | |
15 | ||
16 | =head1 DESCRIPTION | |
17 | ||
18 | C<OPENSSL_CTX> is an internal OpenSSL library context type. | |
19 | Applications may allocate their own, but may also use C<NULL> to use | |
20 | the internal default context with functions that take a C<OPENSSL_CTX> | |
21 | argument. | |
22 | ||
23 | OPENSSL_CTX_new() creates a new OpenSSL library context. | |
ff6da65e MC |
24 | When a non default library context is in use care should be taken with |
25 | multi-threaded applications to properly clean up thread local resources before | |
26 | the OPENSSL_CTX is freed. | |
27 | See L<OPENSSL_thread_stop_ex(3)> for more information. | |

28 | |
29 | OPENSSL_CTX_free() frees the given C<ctx>. | |
30 | ||
31 | =head1 RETURN VALUES | |
32 | ||
33 | OPENSSL_CTX_new() return a library context pointer on success, or | |
34 | C<NULL> on error. | |
35 | ||
36 | OPENSSL_CTX_free() doesn't return any value. | |
37 | ||
38 | =head1 HISTORY | |
39 | ||
40 | OPENSSL_CTX, OPENSSL_CTX_new() and OPENSSL_CTX_free() | |
4674aaf4 | 41 | were added in OpenSSL 3.0. |
