DWARF_EXPR_CURRENT_OFFSET(3)                          Library Functions Manual

NAME
     dwarf_expr_current_offset - retrieve the number of bytes in a location
     expression stream

LIBRARY
     DWARF Access Library (libdwarf, -ldwarf)

SYNOPSIS
     #include <libdwarf.h>

     Dwarf_Unsigned
     dwarf_expr_current_offset(Dwarf_P_Expr expr, Dwarf_Error *err);

DESCRIPTION
     Function dwarf_expr_current_offset() returns the size in bytes of the
     stream representation of a location expression.

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

     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_current_offset() returns the size in
     bytes of the location descriptor's stream representation.  In case of an
     error, function dwarf_expr_current_offset() returns DW_DLV_NOCOUNT and
     sets the argument err.

ERRORS
     Function dwarf_expr_current_offset() can fail with:

     [DW_DLE_ARGUMENT]       Argument expr was NULL.
