# Gerar características da impressão digital

<mark style="color:$warning;">**BOOL WINAPI CmdGenChar(UINT32 iBuffer, UINT8 \_ErrFlag)**</mark>

**Nome da função:** CmdGenChar\
**Descrição da função:** gera arquivos de características a partir da imagem de impressão digital mais recentemente adquirida.\
**Parâmetro:**\
UINT32 iBuffer \[IN], o local de armazenamento dos arquivos de características gerados (no algoritmo eAlg, existem dois buffers para armazenar arquivos de características, CHAR\_BUFFER\_A e CHAR\_BUFFER\_B, respectivamente; 1 significa armazenar em CHAR\_BUFFER\_A, 2 significa armazenar em CHAR\_BUFFER\_B; no algoritmo xAlg, existem três buffers para armazenar arquivos de características, CHAR\_BUFFER\_A, CHAR\_BUFFER\_B e CHAR\_BUFFER\_C; 1 significa armazenar em CHAR\_BUFFER\_A, 2 significa armazenar em CHAR\_BUFFER\_B, 3 significa armazenar em CHAR\_BUFFER\_C).\
UINT8 \*\_ErrFlag \[out], retorna CMD\_RT\_OK em caso de sucesso e CMD\_RT\_GEN\_CHAR\_ERR em caso de falha.\
**Retorno:** TRUE para sucesso, FALSE para falha;

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://portal-integracao.intelbras.com.br/cm-3410-bio/comandos/gerar-caracteristicas-da-impressao-digital.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
