int
dwarf_formflag(Dwarf_Attribute attr, Dwarf_Bool *ret, Dwarf_Error *err);

Function dwarf_formflag() sets the location pointed to by argument ret to 1 if the attribute referenced by argument attr has a non-zero value, or 0 otherwise. The form of argument attr must be one of DW_FORM_flag or DW_FORM_flag_present.

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

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

Function dwarf_formflag() may fail with the following errors:
[]
Either of arguments attr or ret was NULL.
[]
The attribute referenced by argument attr was not of a permitted kind.
