- .TH CURLOPT_CAPATH 3 "17 Jun 2014" "libcurl 7.37.0" "curl_easy_setopt options"
- .SH NAME
- CURLOPT_CAPATH \- specify directory holding CA certificates
- .SH SYNOPSIS
- #include <curl/curl.h>
- CURLcode curl_easy_setopt(CURL *handle, CURLOPT_CAPATH, char *capath);
- .SH DESCRIPTION
- Pass a char * to a zero terminated string naming a directory holding multiple
- CA certificates to verify the peer with. If libcurl is built against OpenSSL,
- the certificate directory must be prepared using the openssl c_rehash utility.
- This makes sense only when used in combination with the
- \fICURLOPT_SSL_VERIFYPEER(3)\fP option. If \fICURLOPT_SSL_VERIFYPEER(3)\fP is
- zero, \fICURLOPT_CAPATH(3)\fP need not even indicate an accessible path. The
- \fICURLOPT_CAPATH(3)\fP function apparently does not work in Windows due to
- some limitation in openssl.
- .SH DEFAULT
- NULL
- .SH PROTOCOLS
- All TLS based protocols: HTTPS, FTPS, IMAPS, POP3, SMTPS etc.
- .SH EXAMPLE
- TODO
- .SH AVAILABILITY
- This option is OpenSSL-specific and does nothing if libcurl is built to use
- GnuTLS. NSS-powered libcurl provides the option only for backward
- compatibility.
- .SH RETURN VALUE
- Returns CURLE_OK if TLS enabled, and CURLE_UNKNOWN_OPTION if not, or
- CURLE_OUT_OF_MEMORY if there was insufficient heap space.
- .SH "SEE ALSO"
- .BR CURLOPT_STDERR "(3), " CURLOPT_DEBUGFUNCTION "(3), "
