	dwarf_get_FORM_CLASS_name is for a libdwarf extension. Not defined by the DWARF standard though the concept is defined in the standard. It seemed essential to invent it for libdwarf to report correctly.

Detailed Description

Given a value you know is one of a particular name category in DWARF2 or later, call the appropriate function and on finding the name it returns DW_DLV_OK and sets the identifier for the value through a pointer. On success these functions return the string corresponding to dw_val_in passed in through the pointer dw_s_out and the value returned is DW_DLV_OK.

The strings returned on sucess are in static storage and must not be freed.

These functions are generated from information in dwarf.h, not hand coded functions.

If DW_DLV_NO_ENTRY is returned the dw_val_in is not known and *s_out is not set. This is unusual.

DW_DLV_ERROR is never returned.

The example referred to offers the suggested way to use functions like these.

Function Documentation

dwarf_get_GNUIKIND_name()

int dwarf_get_GNUIKIND_name	(	unsigned int	dw_val_in,
		const char **	dw_s_out
	)

So we can report things GNU extensions sensibly.

dwarf_get_EH_name()

int dwarf_get_EH_name	(	unsigned int	dw_val_in,
		const char **	dw_s_out
	)

So we can report this GNU extension sensibly.

dwarf_get_FRAME_name()

int dwarf_get_FRAME_name	(	unsigned int	dw_val_in,
		const char **	dw_s_out
	)

The set of register names is unlikely to match your register set, but perhaps this is better than no name.

dwarf_get_GNUIVIS_name()

int dwarf_get_GNUIVIS_name	(	unsigned int	dw_val_in,
		const char **	dw_s_out
	)

So we report a GNU extension sensibly.

dwarf_get_LLEX_name()

int dwarf_get_LLEX_name	(	unsigned int	dw_val_in,
		const char **	dw_s_out
	)

The name is a libdwarf invention for the GNU extension. So we report a GNU extension sensibly.

dwarf_get_MACINFO_name()

int dwarf_get_MACINFO_name	(	unsigned int	dw_val_in,
		const char **	dw_s_out
	)

Used in DWARF2-DWARF4

dwarf_get_MACRO_name()

int dwarf_get_MACRO_name	(	unsigned int	dw_val_in,
		const char **	dw_s_out
	)

Used in DWARF5

dwarf_get_FORM_CLASS_name()

int dwarf_get_FORM_CLASS_name	(	enum Dwarf_Form_Class	dw_fc,
		const char **	dw_s_out
	)

See DWARF5 Table 2.3, Classes of Attribute Value page 23. Earlier DWARF versions have a similar table.
