# CURLOPT\_EGDSOCKET(3)

EGD socket path

## NAME

CURLOPT\_EGDSOCKET - EGD socket path

## SYNOPSIS

```
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_EGDSOCKET, char *path);
```

## DESCRIPTION

Deprecated option. It serves no purpose anymore.

Pass a char pointer to the null-terminated path name to the Entropy Gathering Daemon socket. It is used to seed the random engine for TLS.

The application does not have to keep the string around after setting this option.

## DEFAULT

NULL

## PROTOCOLS

All TLS based protocols: HTTPS, FTPS, IMAPS, POP3S, SMTPS etc.

## EXAMPLE

```
int main(void)
{
  CURL *curl = curl_easy_init();
  if(curl) {
    CURLcode res;
    curl_easy_setopt(curl, CURLOPT_URL, "https://example.com/");
    curl_easy_setopt(curl, CURLOPT_EGDSOCKET, "/var/egd.socket");
    res = curl_easy_perform(curl);
    curl_easy_cleanup(curl);
  }
}
```

## AVAILABILITY

If built with TLS enabled. Only the OpenSSL backend uses this, and only with OpenSSL versions before 1.1.0.

This option was deprecated in 7.84.0.

## RETURN VALUE

Returns CURLE\_OK if TLS is supported, CURLE\_UNKNOWN\_OPTION if not, or CURLE\_OUT\_OF\_MEMORY if there was insufficient heap space.
