DWARF_SET_FRAME_CFA_V... BSD Library Functions Manual DWARF_SET_FRAME_CFA_V...

NAME
     dwarf_set_frame_cfa_value,	dwarf_set_frame_rule_initial_value,
     dwarf_set_frame_rule_table_size, dwarf_set_frame_same_value,
     dwarf_set_frame_undefined_value --	set internal register rule table pa-
     rameters

LIBRARY
     DWARF Access Library (libdwarf, -ldwarf)

SYNOPSIS
     #include <libdwarf.h>

     Dwarf_Half
     dwarf_set_frame_cfa_value(Dwarf_Debug dbg,	Dwarf_Half value);

     Dwarf_Half
     dwarf_set_frame_rule_initial_value(Dwarf_Debug dbg, Dwarf_Half value);

     Dwarf_Half
     dwarf_set_frame_rule_table_size(Dwarf_Debug dbg, Dwarf_Half value);

     Dwarf_Half
     dwarf_set_frame_same_value(Dwarf_Debug dbg, Dwarf_Half value);

     Dwarf_Half
     dwarf_set_frame_undefined_value(Dwarf_Debug dbg, Dwarf_Half value);

DESCRIPTION
     These functions set the parameters	of the internal	register rule table.

     Argument dbg should reference a DWARF debug context allocated using
     dwarf_init(3).

     Argument value should hold	the parameter value to set.

     Function dwarf_set_frame_cfa_value() sets the column number for the CFA
     register rule in the internal register rule table.	 The constant
     DW_FRAME_CFA_COL is the default CFA register column number	for
     DWARF2-only interfaces, and the constant DW_FRAME_CFA_COL3	is the default
     CFA column	number for DWARF3-compatible interfaces.

     Function dwarf_set_frame_rule_initial_value() sets	the initial value of
     the register rules	in the internal	register rule table.  The default ini-
     tial value	is the constant	DW_FRAME_REG_INITIAL_VALUE, defined in the
     header file <libdwarf.h>.

     Function dwarf_set_frame_rule_table_size()	sets the maxmium number	of
     columns of	the internal register rule table.  Argument value should be at
     least as large as the number of real registers in the ABI.

     Function dwarf_set_frame_same_value() sets	the register number represent-
     ing the "same value" register rule.  The default register number for the
     "same value" rule is the constant DW_FRAME_SAME_VAL, defined in the
     header file <libdwarf.h>.

     Function dwarf_set_frame_undefined_value()	sets the register number rep-
     resenting the "undefined" register	rule.  The default register number for
     the "undefined" rule is the constant DW_FRAME_UNDEFINED_VAL, defined in
     the header	file <libdwarf.h>.

RETURN VALUES
     These functions return the	previous value of the parameter	being set.
