int
dwarf_formblock(Dwarf_Attribute attr, Dwarf_Block **ret, Dwarf_Error *err);

Function dwarf_formblock() sets the location pointed to by argument ret to a pointer to a Dwarf_Block structure containing the value of the attribute referenced by argument attr. The form of argument attr must be one of DW_FORM_block, DW_FORM_block1, DW_FORM_block2 or DW_FORM_block4.

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

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

Function dwarf_formblock() 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.
