DWARF_FORMBLOCK(3)	 BSD Library Functions Manual	    DWARF_FORMBLOCK(3)

NAME
     dwarf_formblock --	return the value of a BLOCK attribute

LIBRARY
     DWARF Access Library (libdwarf, -ldwarf)

SYNOPSIS
     #include <libdwarf.h>

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

DESCRIPTION
     Function dwarf_formblock()	sets the location pointed to by	argument ret
     to	a pointer to a Dwarf_Block structure containing	the value of the at-
     tribute 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 descrip-
     tor in case of an error.

   Memory Management
     The memory	area referenced	by the returned	pointer	is managed by the
     DWARF(3) library.	The application	should not attempt to free this	memory
     area.  Portable code may indicate that the	memory area is to be freed by
     using dwarf_dealloc(3).

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

ERRORS
     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.
