  dwarf_get_fde_info_for_all_regs(Dwarf_Fde
    fde, Dwarf_Addr pc,
    Dwarf_Regtable *reg_table, Dwarf_Addr
    *row_pc, Dwarf_Error *err);
dwarf_get_fde_info_for_all_regs() retrieves a
  row from the register rule table associated with the given FDE descriptor.
Argument fde should reference a valid DWARF FDE descriptor.
Argument pc should hold the program counter address to be used to locate the desired table row.
Argument reg_table should point to a Dwarf_Regtable descriptor which will hold the returned table row of register rules.
Argument row_pc should point to a location which will be set to the lowest program counter address associated with the table row.
If argument err is not NULL, it will be used to store error information in case of an error.
The Dwarf_Regtable descriptor is defined in
    the header file
    <libdwarf.h>:
typedef struct {
	struct {
		Dwarf_Small	dw_offset_relevant;
		Dwarf_Half	dw_regnum;
		Dwarf_Addr	dw_offset;
	} rules[DW_REG_TABLE_SIZE];
} Dwarf_Regtable;
For each of the register rules returned, the dw_offset_relevant field is set to 1 if the register rule has a offset value. The dw_regnum field is set to the register number associated with the regsiter rule. The dw_offset field is set to the offset value associated with the register rule.
The number of register columns returned is either the constant
    value DW_REG_TABLE_SIZE as defined in the header
    file <libdwarf.h>, or the
    value set by function
    dwarf_set_frame_rule_table_size(3),
    whichever is smaller.
dwarf_get_fde_info_for_all_regs() is deprecated
  since it only supports DWARF2 frame sections. Applications should instead use
  function
  dwarf_get_fde_info_for_all_regs3(3)
  which supports both DWARF2 and DWARF3 frame sections.
dwarf_get_fde_info_for_all_regs() returns
  DW_DLV_OK when it succeeds. In case of an error, it
  returns DW_DLV_ERROR and sets the argument
  err.
dwarf_get_fde_info_for_all_regs() can fail
  with:
