**#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](#ARGUMENTS)

should contain a PKCS 11 URL

[gnutls\_pkcs11\_token\_info\_t ttype](#gnutls_pkcs11_token_info_t)

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

# [DESCRIPTION](#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**.
