.SH NAME
|
|
|
|
|
CURLOPT_PROXY_CAPATH \- directory holding HTTPS proxy CA certificates
|
|
|
|
|
.SH SYNOPSIS
|
|
|
|
|
.nf
|
|
|
|
|
#include <curl/curl.h>
|
|
|
|
|
|
|
|
|

CURLcode curl_easy_setopt(CURL *handle, CURLOPT_PROXY_CAPATH, char *capath);

|
.SH DESCRIPTION
|
|
|
|
|
Pass a char pointer to a null\-terminated string naming a directory holding
|
|
|
|
|
multiple CA certificates to verify the HTTPS proxy with. If libcurl is built
|
|
|
|
|
against OpenSSL, the certificate directory must be prepared using the OpenSSL
|
|
|
|
|
\fBc_rehash\fP utility. This makes sense only when
|
|
|
|
|
\fICURLOPT_PROXY_SSL_VERIFYPEER(3)\fP is enabled (which it is by default).
|
|
|
|
|
|
|
|
|
|
The application does not have to keep the string around after setting this
|
|
|
|
|
option.
|
|
|
|
|
|
|
|
|
|
The default value for this can be figured out with \fICURLINFO_CAPATH(3)\fP.
|
|
|
|
|
.SH DEFAULT
|
|
|
|
|
NULL
|
|
|
|
|
.SH PROTOCOLS

2024-03-30 12:28:04 -06:00
