53 is a full library context in its own right, but will have all the same providers
54 available to it that are available in the application library context (without
56 application library context then this will be automatically mirrored in the
57 child library context.
59 In addition providers that are not loaded in the parent library context can be
60 explicitly loaded into the child library context independently from the parent
61 library context. Providers loaded independently in this way will not be mirrored
62 in the parent library context and will not be affected if the parent library
63 context subsequently loads the same provider.

74 In addition to providers, a child library context will also mirror the default

77 library context then the new properties will override anything from the parent

99 OSSL_LIB_CTX_set0_default() sets the default OpenSSL library context to be

102 default library context with a subsequent call of this function. If I<ctx> is
103 NULL then no change is made to the default library context, but a pointer to
104 the current library context is still returned. On a successful call of this
