.SH DESCRIPTION
.IX Header "DESCRIPTION"
The macros \fBOPENSSL_FILE\fR and \fBOPENSSL_LINE\fR
typically yield the current filename and line number during C compilation.
When \fBOPENSSL_NO_FILENAMES\fR is defined they yield \fB""\fR and \fB0\fR, respectively.
.PP
The macro \fBOPENSSL_FUNC\fR attempts to yield the name of the C function
currently being compiled, as far as language and compiler versions allow.
Otherwise, it yields "(unknown function)".
.PP
The macro \fBOPENSSL_MSTR\fR yields the expansion of the macro given as argument,
which is useful for concatenation with string constants.
The macro \fBOPENSSL_MSTR_HELPER\fR is an auxiliary macro for this purpose.

.SH HISTORY

\&\fBOPENSSL_FUNC\fR, \fBOPENSSL_MSTR\fR, and \fBOPENSSL_MSTR_HELPER\fR
were added in OpenSSL 3.0.
