status.i4.v = str_length_c(string.i1a.r, maximum_length.i4.v)

	This routine returns the length of a string.

	string		string to check
	maximum_length	maximum allowable return length
			(Note: If a value of STR_NO_LIMIT is passed,
			 maximum length will be set to infinity for a
			 C string or the descriptor length field value
			 for a string passed by descriptor.)

	This function returns status values as follows:

	length of the string
	(A value of 0 is returned if "string" is a null pointer.)

	This function requires the following include files:


	Related functions:

	str_nonblank_length_c, str_delimited_length_c, lenchs(_c), strlen

	C/C++ usage:

	static const char	string[] = "Determine the length of this string.";
	int	status;
	int	maximum_length = 9;

	status = str_length_c(string,maximum_length);
