Use \fIcurl_easy_escape(3)\fP instead! This function converts the given input \fBstring\fP to a URL encoded string and return that as a new allocated string. All input characters that are not a\-z, A\-Z or 0\-9 are converted to their "URL escaped" version (\fB%NN\fP where \fBNN\fP is a two\-digit hexadecimal number). If the \fBlength\fP argument is set to 0, \fIcurl_escape(3)\fP uses strlen() on \fBstring\fP to find out the size. You must \fIcurl_free(3)\fP the returned string when you are done with it. .SH PROTOCOLS All .SH EXAMPLE .nf int main(void) { char *output = curl_escape("data to convert", 15); if(output) { printf("Encoded: %s\\n", output); curl_free(output); } } .fi .SH AVAILABILITY Since 7.15.4, \fIcurl_easy_escape(3)\fP should be used. This function might be removed in a future release. .SH RETURN VALUE A pointer to a null\-terminated string or NULL if it failed. .SH SEE ALSO .BR curl_free (3), .BR curl_unescape (3)
