# radcli\_ctx\_new(3)

Create an empty context, ready for radcli\_ctx\_set\_opt\_str()/ \_set\_opt\_int() and radcli\_ctx\_apply() the fully programmatic ("backup") way to configure radcli without a config file on disk.

## NAME

radcli\_ctx\_new - Create an empty context, ready for radcli\_ctx\_set\_opt\_str()/ \_set\_opt\_int() and radcli\_ctx\_apply()  the fully programmatic ("backup") way to configure radcli without a config file on disk.

## SYNOPSIS

```
#include <radcli/>

radcli_ctx * radcli_ctx_new(
    unsigned flags
);
```

## DESCRIPTION

Allocates a context with no server, secret, or transport configured yet  radcli\_ctx\_apply() must succeed before it is usable for a request. Also loads the built-in RFC 2865/2866/2869 dictionary, the same one radcli\_ctx\_read\_config() always loads, unless RADCLI\_CTX\_NO\_BUILTIN\_DICT is set in flags  so radcli\_dict\_lookup\_num() is non-NULL for well-known attributes right away, without a separate radcli\_ctx\_read\_dictionary() call.

## PARAMETERS

- **flags**

  a bitwise OR of radcli\_ctx\_flags, or 0 for the common case.

## RETURN VALUE

the new context, or NULL on allocation failure, an unknown flags bit, or a failure loading the built-in dictionary.
