XSLT_RVT_FUNC_RESULT

#define XSLT_RVT_FUNC_RESULT   ((void *)2)

XSLT_RVT_FUNC_RESULT:

Definition at line 55 of file variables.h.

XSLT_RVT_GLOBAL

#define XSLT_RVT_GLOBAL   ((void *)3)

XSLT_RVT_GLOBAL:

RVT is part of a global variable.

XSLT_RVT_LOCAL

#define XSLT_RVT_LOCAL   ((void *)1)

XSLT_RVT_LOCAL:

RVT is destroyed after the current instructions ends.
