.TH curl_easy_escape 3 "7 April 2006" "libcurl" "libcurl"
|
|
.SH NAME
|
|
curl_easy_escape - URL encodes the given string
|
|
.SH SYNOPSIS
|
|
.nf
|
|
#include <curl/curl.h>
|
|
|
|
char *curl_easy_escape(CURL *curl, const char *string, int length);
|
|
.fi
|
|
.SH DESCRIPTION
|
|
This function converts the given input \fIstring\fP 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 (\fB%NN\fP where \fBNN\fP is a two-digit hexadecimal number).
|
|
|
|
If \fIlength\fP is set to 0 (zero), \fIcurl_easy_escape(3)\fP uses strlen() on
|
|
the input \fIstring\fP to find out the size. This function does not accept
|
|
input strings longer than \fBCURL_MAX_INPUT_LENGTH\fP (8 MB).
|
|
|
|
Since 7.82.0, the \fBcurl\fP parameter is ignored. Prior to that there was
|
|
per-handle character conversion support for some old operating systems such as
|
|
TPF, but it was otherwise ignored.
|
|
|
|
You must \fIcurl_free(3)\fP the returned string when you are done with it.
|
|
.SH ENCODING
|
|
libcurl is typically not aware of, nor does it care about, character
|
|
encodings. \fIcurl_easy_escape(3)\fP encodes the data byte-by-byte into the
|
|
URL encoded version without knowledge or care for what particular character
|
|
encoding the application or the receiving server may assume that the data
|
|
uses.
|
|
|
|
The caller of \fIcurl_easy_escape(3)\fP must make sure that the data passed in
|
|
to the function is encoded correctly.
|
|
.SH EXAMPLE
|
|
.nf
|
|
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);
|
|
}
|
|
.fi
|
|
.SH AVAILABILITY
|
|
Added in 7.15.4 and replaces the old \fIcurl_escape(3)\fP function.
|
|
.SH RETURN VALUE
|
|
A pointer to a null-terminated string or NULL if it failed.
