DESCRIPTION

     These functions return the symbolic name of a numeric DWARF constant.

     Argument val specifies the numeric value whose symbolic name is desired.

     Argument str should point to a location which will hold the returned NUL-terminated string containing the symbolic name of the specified
     value.

     The list of functions and the DWARF constants that they accept are:

     dwarf_get_ACCESS_name()	  DW_ACCESS_* constants.
     dwarf_get_AT_name()	  DW_AT_* constants.
     dwarf_get_ATE_name()	  DW_ATE_* constants.
     dwarf_get_CC_name()	  DW_CC_* constants.
     dwarf_get_CFA_name()	  DW_CFA_* constants.
     dwarf_get_CHILDREN_name()	  DW_CHILDREN_* constants.
     dwarf_get_DS_name()	  DW_DS_* constants.
     dwarf_get_DSC_name()	  DW_DSC_* constants.
     dwarf_get_EH_name()	  DW_EH_PE_* constants.
     dwarf_get_END_name()	  DW_END_* constants.
     dwarf_get_FORM_name()	  DW_FORM_* constants.
     dwarf_get_ID_name()	  DW_ID_* constants.
     dwarf_get_INL_name()	  DW_INL_* constants.
     dwarf_get_LANG_name()	  DW_LANG_* constants.
     dwarf_get_LNE_name()	  DW_LNE_* constants.
     dwarf_get_LNS_name()	  DW_LNS_* constants.
     dwarf_get_MACINFO_name()	  DW_MACINFO_* constants.
     dwarf_get_OP_name()	  DW_OP_* constants.
     dwarf_get_ORD_name()	  DW_ORD_* constants.
     dwarf_get_TAG_name()	  DW_TAG_* constants.
     dwarf_get_VIRTUALITY_name()  DW_VIRTUALITY_* constants.
     dwarf_get_VIS_name()	  DW_VIS_* constants.

RETURN VALUES

     These functions return DW_DLV_OK on success. If the DWARF constant denoted by argument val is not recognized, these function return
     DW_DLV_NO_ENTRY.
