.IX Header "DESCRIPTION"
Applications can create and use their own stacks by placing any of the macros
described below in a header file. These macros define typesafe inline
functions that wrap around the utility \fBOPENSSL_sk_\fR \s-1API.\s0
In the description here, \fI\s-1TYPE\s0\fR is used
as a placeholder for any of the OpenSSL datatypes, such as \fIX509\fR.
