=head1 SYNOPSIS

|
|
|
||
|
|
#include <openssl/deserializer.h>
|

|
||

typedef struct ossl_deserializer_ctx_st OSSL_DESERIALIZER_CTX;

=head1 DESCRIPTION
|
||
|
|
|
||
|
|
B<OSSL_DESERIALIZER_CTX> is a context with which B<OSSL_DESERIALIZER>
|
||
|
|
operations are performed. The context typically holds values, both
|
||
|
|
internal and supplied by the application, which are useful for the
|
||
|
|
implementations supplied by providers.
|
||
|
|
|
||
|
|
OSSL_DESERIALIZER_CTX_new() creates a new empty B<OSSL_DESERIALIZER_CTX>.
|
||
|
|
|
||
|
|
OSSL_DESERIALIZER_settable_ctx_params() returns an L<OSSL_PARAM(3)>
|
||
|
|
array of parameter descriptors.
|
||
|
|
|
||
|
|
OSSL_DESERIALIZER_CTX_set_params() attempts to set parameters specified
|
||
|
|
with an L<OSSL_PARAM(3)> array I<params>. These parameters are passed
|
||
|
|
to all deserializers that have been added to the I<ctx> so far.
|
||
|
|
Parameters that an implementation doesn't recognise should be ignored
|
||
|
|
by it.
|
||
|
|
|
||
|
|
OSSL_DESERIALIZER_CTX_free() frees the given context I<ctx>.
|
||
|
|
|
||
|
|
=head1 RETURN VALUES
|
||
|
|
|
||
|
|
OSSL_DESERIALIZER_CTX_new() returns a pointer to a
|
||
|
|
B<OSSL_DESERIALIZER_CTX>, or NULL if the context structure couldn't be
|
||
|
|
allocated.
|
||
|
|
|
||
|
|
OSSL_DESERIALIZER_settable_ctx_params() returns an L<OSSL_PARAM(3)>
|
||
|
|
array, or NULL if none is available.
|
||
|
|
|
||
|
|
OSSL_DESERIALIZER_CTX_set_params() returns 1 if all recognised
|
||
|
|
parameters were valid, or 0 if one of them was invalid or caused some
|
||
|
|
other failure in the implementation.
