gnutls_pkcs11_obj_get_info - API function

#include <gnutls/pkcs11.h>

int gnutls_pkcs11_obj_get_info(gnutls_pkcs11_obj_t obj, gnutls_pkcs11_obj_info_t itype, void * output, size_t * output_size);

should contain a gnutls_pkcs11_obj_t type
Denotes the type of information requested
where output will be stored
contains the maximum size of the output buffer and will be overwritten with the actual size.

This function will return information about the PKCS11 certificate such as the label, id as well as token information where the key is stored.

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.

In versions previously to 3.6.0 this function included the null terminator to output_size . After 3.6.0 the output size doesn't include the terminator character.

GNUTLS_E_SUCCESS (0) on success or a negative error code on error.
