DWARF_FORMSTRING(3)	 BSD Library Functions Manual	   DWARF_FORMSTRING(3)

NAME
     dwarf_formstring -- return	the value of a STRING class attribute

LIBRARY
     DWARF Access Library (libdwarf, -ldwarf)

SYNOPSIS
     #include <libdwarf.h>

     int
     dwarf_formstring(Dwarf_Attribute attr, char **ret,	Dwarf_Error *err);

DESCRIPTION
     Function dwarf_formstring() sets the location pointed to by argument ret
     to	a pointer to a NUL-terminated string containing	the value of the at-
     tribute referenced	by argument attr.  The form of argument	attr must be
     one of DW_FORM_string or DW_FORM_strp.

     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 directly free
     this memory area.

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

ERRORS
     Function dwarf_formstring() 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.
