curl_easy_escape(3) libcurl Manual curl_easy_escape(3) NAME curl_easy_escape - URL encodes the given string SYNOPSIS #include <curl/curl.h> char *curl_easy_escape(CURL *curl, const char *string, int length); DESCRIPTION This function converts the given input string to a URL encoded string and returns that as a new allocated string. All input characters that are not a-z, A-Z, 0-9, '-', '.', '_' or '~' are converted to their "URL escaped" version (%NN where NN is a two-digit hexadecimal number). If length is set to 0 (zero), curl_easy_escape(3) uses strlen() on the input string to find out the size. This function does not accept input strings longer than CURL_MAX_INPUT_LENGTH (8 MB). You must curl_free(3) the returned string when you are done with it. ENCODING libcurl is typically not aware of, nor does it care about, character encodings. curl_easy_escape(3) encodes the data byte-by-byte into the URL encoded version without knowledge or care for what particular char- acter encoding the application or the receiving server may assume that the data uses. The caller of curl_easy_escape(3) must make sure that the data passed in to the function is encoded correctly. EXAMPLE CURL *curl = curl_easy_init(); if(curl) { char *output = curl_easy_escape(curl, "data to convert", 15); if(output) { printf("Encoded: %s\n", output); curl_free(output); } curl_easy_cleanup(curl); } AVAILABILITY Added in 7.15.4 and replaces the old curl_escape(3) function. RETURN VALUE A pointer to a null-terminated string or NULL if it failed.
