DWARF_EXPR_CURRENT_OF... BSD Library Functions Manual DWARF_EXPR_CURRENT_OF... 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.
