=head1 NAME

TS_RESP_CTX_new_ex, TS_RESP_CTX_new,
TS_RESP_CTX_free - Timestamp response context object creation


=head1 SYNOPSIS

 #include <openssl/ts.h>

 TS_RESP_CTX *TS_RESP_CTX_new_ex(OSSL_LIB_CTX *libctx, const char *propq);
 TS_RESP_CTX *TS_RESP_CTX_new(void);
 void TS_RESP_CTX_free(TS_RESP_CTX *ctx);

=head1 DESCRIPTION

Creates a response context that can be used for generating responses.

TS_RESP_CTX_new_ex() allocates and initializes a TS_RESP_CTX structure with a
library context of I<libctx> and a property query of I<propq>.
The library context and property query can be used to select which providers
supply the fetched algorithms.

TS_RESP_CTX_new() is similar to TS_RESP_CTX_new_ex() but sets the library context
and property query to NULL. This results in the default (NULL) library context
being used for any operations requiring algorithm fetches.

TS_RESP_CTX_free() frees the B<TS_RESP_CTX> object I<ctx>.

=head1 RETURN VALUES

If the allocation fails, TS_RESP_CTX_new_ex() and TS_RESP_CTX_new() return NULL,
otherwise it returns a pointer to the newly allocated structure.

=head1 HISTORY

The function TS_RESP_CTX_new_ex() was added in OpenSSL 3.0.
