# gnutls\_pkcs11\_token\_get\_info(3)

API function

## NAME

gnutls\_pkcs11\_token\_get\_info - API function

## SYNOPSIS

**#include \<gnutls/pkcs11.h\>**

**int gnutls\_pkcs11\_token\_get\_info(const char \*** *url***, gnutls\_pkcs11\_token\_info\_t** *ttype***, void \*** *output***, size\_t \*** *output\_size***);**

## ARGUMENTS

- const char \* url

  should contain a PKCS 11 URL

- gnutls\_pkcs11\_token\_info\_t ttype

  Denotes the type of information requested

- void \* output

  where output will be stored

- size\_t \* output\_size

  contains the maximum size of the output buffer and will be overwritten with the actual size.

## DESCRIPTION

This function will return information about the PKCS 11 token such as the label, id, etc.

When output is text, a null terminated string is written to  *output* and its string length is written to  *output\_size* (without null terminator). If the buffer is too small,  *output\_size* will contain the expected buffer size (with null terminator for text) and return **GNUTLS\_E\_SHORT\_MEMORY\_BUFFER**.

## RETURNS

**GNUTLS\_E\_SUCCESS** (0) on success or a negative error code on error.

## SINCE

2\.12.0
