NAME

       mstl_init - Initializing and freeing MSTraceList structures

SYNOPSIS

       #include <libmseed.h>

       MSTrace      *mstl_init ( MSTrace *mstl );

       void          mstl_free ( MSTrace **ppmstl, flag freeprvtptr );

DESCRIPTION

       mstl_init  will initialize a MSTraceList structure.  If the mstl parameter is not NULL the
       structure will be cleared before being reallocated any  memory  allocated  for  associated
       MSTraceID and relate sub-structures will be freed.

       mstl_free  will  free  all  memory  associated  with  a  MSTraceList structure and set the
       structure pointer (*ppmstl) to 0.  If the freeprvtptr flag is true any memory  pointed  to
       by the prvtptr members of the MSTraceID or MSTraceSeg structures.

RETURN VALUES

       mstl_init returns a pointer to the MSTraceList structure initialized on success or NULL on
       error.
