.SH SYNOPSIS
.IX Header "SYNOPSIS"
.Vb 1
\& #include <openssl/self_test.h>
\&
\& void OSSL_SELF_TEST_set_callback(OSSL_LIB_CTX *ctx, OSSL_CALLBACK *cb, void *cbarg);

.SH DESCRIPTION
.IX Header "DESCRIPTION"
Set or gets the optional application callback (and the callback argument) that
is called during self testing.
The application callback \fBOSSL_CALLBACK\fR\|(3) is associated with a \fBOSSL_LIB_CTX\fR.
The application callback function receives information about a running self test,
and may return a result to the calling self test.
See \fBopenssl\-core.h\fR\|(7) for further information on the callback.
.SH "RETURN VALUES"
.IX Header "RETURN VALUES"
\&\fBOSSL_SELF_TEST_get_callback()\fR returns the callback and callback argument that
has been set via \fBOSSL_SELF_TEST_set_callback()\fR for the given library context
\&\fIctx\fR.
These returned parameters will be NULL if \fBOSSL_SELF_TEST_set_callback()\fR has
not been called.
