# SSL\_CONF\_cmd\_argv(3ssl)

SSL configuration command line processing

## NAME

SSL\_CONF\_cmd\_argv - SSL configuration command line processing

## SYNOPSIS

```
 #include <openssl/ssl.h>
 int SSL_CONF_cmd_argv(SSL_CONF_CTX *cctx, int *pargc, char ***pargv);
```

## DESCRIPTION

The function **SSL\_CONF\_cmd\_argv()** processes at most two command line arguments from **pargv** and **pargc**. The values of **pargv** and **pargc** are updated to reflect the number of command options processed. The **pargc** argument can be set to **NULL** if it is not used.

## RETURN VALUES

**SSL\_CONF\_cmd\_argv()** returns the number of command arguments processed: 0, 1, 2 or a negative error code.

If -2 is returned then an argument for a command is missing.

If -1 is returned the command is recognised but couldn't be processed due to an error: for example a syntax error in the argument.
