||
|
|
.SH NAME
|
||
|
|
curl_escape - URL encodes the given string
|
||
|
|
.SH SYNOPSIS
|
||
|
|
.nf
|
||
|
|
#include <curl/curl.h>
|
||
|
|
|
||
|
|
char *curl_escape(const char *string, int length);
|
||
|
|
.fi
|
||
|
|
.SH DESCRIPTION
|
||
|
|
Obsolete function. 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 EXAMPLE
|
||
|
|
.nf
|
||
|
|
char *output = curl_escape("data to convert", 15);
|
||
|
|
if(output) {
|
||
|
|
printf("Encoded: %s\\n", output);
|
||
|
|
curl_free(output);
|
||
|
|
}
|
||
|
|
.fi
|
||
|
|
.SH AVAILABILITY
|
||
|
|

|
||
|
|
removed in a future release.
|
||
|
|

|
A pointer to a null-terminated string or NULL if it failed.
