util_uri_escape() Function

The util_uri_escape function converts any special characters in the URI into the URI format. This format is %XX, where XX is the hexadecimal equivalent of the ASCII character. This function 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);

Return Values

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 it. If d is NULL, the function allocates a properly sized string and copies the formatted special characters into the new string, then returns it.

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.
