DWARF_FORMSIG8(3)					   BSD Library Functions Manual 					 DWARF_FORMSIG8(3)

NAME

     dwarf_formsig8 -- return the 64-bit type signature for a DWARF type

LIBRARY

     DWARF Access Library (libdwarf, -ldwarf)

SYNOPSIS

     #include <libdwarf.h>

     int
     dwarf_formsig8(Dwarf_Attribute attr, Dwarf_Sig8 *ret, Dwarf_Error *err);

DESCRIPTION

     Function dwarf_formsig8() sets the location pointed to by argument ret to the 64-bit type signature that is the value of the attribute refer-
     enced by argument attr.  The form of argument attr must be DW_FORM_ref_sig8.

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

RETURN VALUES

     Function dwarf_formsig8() returns DW_DLV_OK on success.  In case of an error, it returns DW_DLV_ERROR and sets argument err.

ERRORS

     Function dwarf_formsig8() 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.

SEE ALSO

HISTORY

     Type signatures were added in version 4 of the DWARF specification.

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
     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.

   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 mem-
     ory area.	Portable code may indicate that the memory area is to be freed by 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.
