Sun Java System Web Server 6.1 SP7 NSAPI Programmer's Guide


The util_uri_escape function converts any special characters in the URI into the URI format (%XX, where XX is the hexadecimal equivalent of the ASCII character), and returns the escaped string. The special characters are %?#:+&*"<>, space, carriage return, and line feed.

Use util_uri_escape before sending a URI back to the client.


char *util_uri_escape(char *d, char *s);


The string (possibly newly allocated) with escaped characters replaced.


char *d is a string. If d is not NULL, the function copies the formatted string into d and returns d. If d is NULL, the function allocates a properly sized string and copies the formatted special characters into the new string, then returns d.

The util_uri_escape function does not check bounds for the parameter d. Therefore, if d is not NULL, it should be at least three times as large as the string s.

char *s is the string containing the original unescaped URI.
