NAME         top

       gnutls_pkcs11_obj_get_info - API function

SYNOPSIS         top

       #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);

ARGUMENTS         top

       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.

DESCRIPTION         top

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

       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

       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.

RETURNS         top

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