dwarf_formsig8 – return the 64-bit type signature for a DWARF type

LIBRARY SYNOPSIS DESCRIPTION RETURN VALUES ERRORS SEE ALSO HISTORY

DWARF Access Library (libdwarf, -ldwarf)

#include <libdwarf.h>

int
dwarf_formsig8(Dwarf_Attribute attr, Dwarf_Sig8 *ret, Dwarf_Error *err);

Function dwarf_formsig8() sets the location pointed to by argument ret to the 64-bit type signature that is the value of the attribute referenced by argument attr. The form of argument attr must be DW_FORM_ref_sig8.

If argument err is not NULL, it will be used to return an error descriptor in case of an error.

Function dwarf_formsig8() returns DW_DLV_OK on success. In case of an error, it returns DW_DLV_ERROR and sets argument err.

Function dwarf_formsig8() may fail with the following errors:

[DW_DLE_ARGUMENT]	Either of arguments attr or ret was NULL.
[DW_DLE_ATTR_FORM_BAD]	The attribute referenced by argument attr was not of a permitted kind.

Type signatures were added in version 4 of the DWARF specification.
