# Buscar template de impressão digital

<mark style="color:$warning;">**BOOL WINAPI CmdSearchChar(UINT32 iBuffer, UINT16 \*\_RetMbIndex, UINT16**</mark><mark style="color:$warning;">**&#x20;**</mark>*<mark style="color:$warning;">**\_RetScore, UINT8 \_ErrFlag)**</mark>*

**Nome da função:** CmdSearchChar\
Descrição da função: busca templates de impressão digital já existentes na FLASH.\
**Parâmetro:**\
UINT32 iBuffer \[IN], o local dos arquivos de características a serem buscados (no algoritmo eAlg, existem dois buffers para 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).\
UINT16 \*\_RetMbIndex \[OUT], retorna o número de índice do mesmo template de impressão digital, caso seja encontrado.\
UINT16 \*\_RetScore \[OUT], no algoritmo eAlg, se o mesmo template de impressão digital for encontrado, retorna a pontuação de correspondência. No algoritmo xAlg, se o mesmo template de impressão digital for encontrado, a pontuação de correspondência é 100; caso contrário, a pontuação é 0.\
UINT8 \*\_ErrFlag \[out], a FLASH retorna CMD\_RT\_OK se houver a mesma impressão digital; caso contrário, retorna CMD\_RT\_FINGER\_SEARCH\_FAILE.\
**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/buscar-template-de-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.
