# SYNOPSIS

#include <libdwarf.h>

int
dwarf_diename(Dwarf_Die die, char **ret_name, Dwarf_Error *err);

# DESCRIPTION

Function dwarf_diename() retrieves a pointer to the NUL-terminated string associated with the DW_AT_name attribute of the debugging information entry descriptor referenced by argument die. If the pointer was successfully retrieved, it is stored in the location pointed to by argument ret_name.

# RETURN VALUES

Function dwarf_diename() returns DW_DLV_OK on success.

If the debugging information entry descriptor denoted by argument die does not contain a DW_AT_name attribute, the function returns DW_DLV_NO_ENTRY and sets argument err. For other errors, it returns DW_DLV_ERROR and sets argument err.

# ERRORS

Function dwarf_diename() can fail with the following errors:

[DW_DLE_ARGUMENT]
  Either of arguments die or ret_name was NULL.
[DW_DLE_NO_ENTRY]
  Argument die had no DW_AT_name attribute.
