.BI "MSTrace      *\fBmstl_init\fP ( MSTrace *" mstl " );"

relate sub-structures will be freed.

\fBmstl_free\fP will free all memory associated with a MSTraceList
structure and set the structure pointer (*\fIppmstl\fP) to 0.  If the
\fIfreeprvtptr\fP flag is true any memory pointed to by the
\fIprvtptr\fP members of the MSTraceID or MSTraceSeg structures.
