# radcli\_ctx\_read\_dictionary\_from\_buffer(3)

Load an additional attribute dictionary from an in-memory buffer.

## NAME

radcli\_ctx\_read\_dictionary\_from\_buffer - Load an additional attribute dictionary from an in-memory buffer.

## SYNOPSIS

```
#include <radcli/>

int radcli_ctx_read_dictionary_from_buffer(
    radcli_ctx  *ctx,
    const char  *buf,
    size_t       size
);
```

## DESCRIPTION

The from-buffer counterpart to radcli\_ctx\_read\_dictionary(), for a caller that has dictionary text already in memory rather than in a file (e.g. a small, program-defined supplemental dictionary)  added so a radcli2.h-only caller is not forced to reach into radcli.h's rc\_read\_dictionary\_from\_buffer() for this one operation.

## PARAMETERS

- **ctx**

  a context from radcli\_ctx\_new() or radcli\_ctx\_read\_config().

- **buf**

  the dictionary text.

- **size**

  buf's length in bytes.

## RETURN VALUE

0 on success, -1 on failure (a parse error, including a conflicting redefinition of an already-loaded attribute).
