curl_unescape - Man Page
URL decodes the given string
Synopsis
#include <curl/curl.h> char *curl_unescape(const char *input, int length);
Description
Obsolete function. Use curl_easy_unescape(3) instead!
This function will convert the URL encoded string input 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(3) will use strlen() on input to find out the size.
You must curl_free(3) the returned string when you are done with it.
Example
CURL *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); } }
Availability
Since 7.15.4, curl_easy_unescape(3) should be used. This function will be removed in a future release.
Return Value
A pointer to a null-terminated string or NULL if it failed.
