I don't see anything wrong with STRLEN perl_len; SvPV(sv, perl_len); The macro SvPV will always assign the length to perl_len. (I'm ignoring the return value from it because you didn't seem to need the pointer) To be portable you need to ensure that the type of the second argument to SvPV is STRLEN, else your code will have problems on 64 bit platforms. The macro passes a pointer to the variable into a function, and if the variable is 32 bits when 64 is expected, or vice versa, you'll get corrupt values. Nicholas Clark
