gnutls_pkcs11_obj_get_info - Man Page

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);


gnutls_pkcs11_obj_t obj

should contain a gnutls_pkcs11_obj_t type

gnutls_pkcs11_obj_info_t itype

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.


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.
