DWARF_HASATTR(3) BSD Library Functions Manual DWARF_HASATTR(3) NAME dwarf_hasattr -- check for the presence of an attribute LIBRARY DWARF Access Library (libdwarf, -ldwarf) SYNOPSIS #include <libdwarf.h> int dwarf_hasattr(Dwarf_Die die, Dwarf_Half attr, Dwarf_Bool *ret_bool, Dwarf_Error *err); DESCRIPTION Function dwarf_hasattr() tests whether the debugging information entry referenced in argument die contains the attribute named by argument attr. Legal values for argument attr are those denoted by the DW_AT_* constants in the DWARF specification. If the named attribute is present in the debugging information entry, function dwarf_hasattr() returns a non-zero value in the location pointed to by argument ret_bool. If the named attribute is not present, a zero is written instead. If argument err is not NULL, it will be used to return an error descrip- tor in case of an error. RETURN VALUES On success, function dwarf_hasattr() returns DW_DLV_OK. In case of an error, it returns DW_DLV_ERROR and sets argument err. ERRORS Function dwarf_hasattr() can fail with the following error: [DW_DLE_ARGUMENT] Either of argument die or ret_bool was NULL.
