Thanks a lot Rasmus, I have just (wrongly) assumed that the
convert_to_string function tries to search for the 0 termination
character.
Thanks,

I am developing a PHP plugin using PHP 4.4 SDK (not 5) and I need

Until now to access parameters I am using the
zend_get_parameters_ex routine and then the various
convert_to_something routines.
I think I can't use the convert_to_string function because my
parameters is binary data but I wonder what I can use in this
case, I need the raw char * pointer and not a C string...
I think you are a bit confused. There is no such thing as a C
string. A string in C is simply an array of chars or a char *. In
order to deal with binary data you have to carry the length of the
data around with the char * which is exactly what PHP does.
Without that you have no way of knowing how much binary data you
have. So in short, you should be fine using the standard PHP API
string.
