DWARF_EXPR_INTO_BLOCK(3) BSD Library Functions Manual DWARF_EXPR_INTO_BLOCK(3)

NAME
     dwarf_expr_into_block -- retrieve the byte	stream for a location expres-
     sion

LIBRARY
     DWARF Access Library (libdwarf, -ldwarf)

SYNOPSIS
     #include <libdwarf.h>

     Dwarf_Addr
     dwarf_expr_into_block(Dwarf_P_Expr	expr, Dwarf_Unsigned *length,
	 Dwarf_Error *err);

DESCRIPTION
     Function dwarf_expr_into_block() retrieves	the byte stream	representation
     of	a location expression.

     Argument expr should reference a location expression descriptor allocated
     using dwarf_new_expr(3).

     Argument length should point to a location	which will hold	the size in
     bytes of the retrieved byte stream.

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

RETURN VALUES
     On	success, function dwarf_expr_into_block() returns the address of the
     first byte	of the generated byte stream.  In case of an error, function
     dwarf_expr_into_block() returns DW_DLV_BADADDR and	sets the argument err.

ERRORS
     Function dwarf_expr_into_block() can fail with:

     [DW_DLE_ARGUMENT]	One of the arguments expr or length was	NULL.

     [DW_DLE_MEMORY]	An out of memory condition was encountered during the
			execution of the function.
