NAMEcurl_unescape - URL decodes the given string
SYNOPSIS#include <curl/curl.h>
char *curl_unescape( const char *url, int length);
DESCRIPTIONObsolete function. Use curl_easy_unescape(3) instead! This function will convert the given URL encoded input string to a "plain string" and return that as a new allocated string. All input characters that are URL encoded (%XX where XX is a two-digit hexadecimal number) will be converted to their plain text versions. If the 'length' argument is set to 0, curl_unescape() will use strlen() on the input 'url' string to find out the size. You must curl_free(3) the returned string when you are done with it.
EXAMPLECURL *curl = curl_easy_init();
if(curl) {
int decodelen;
char *decoded = curl_unescape("%63%75%72%6c", 12, &decodelen);
if(decoded) {
/* do not assume printf() works on the decoded data! */
printf("Decoded: ");
/* ... */
curl_free(decoded);
}
}
AVAILABILITYSince 7.15.4, curl_easy_unescape(3) should be used. This function will be removed in a future release.
RETURN VALUEA pointer to a null-terminated string or NULL if it failed.
