NAME

       Tss2_TctiLdr_GetInfo  -  Query  TctiLdr  library  for the TSS2_TCTI_INFO structure associated with a TCTI
       library.

SYNOPSIS

       #include <tss2/tss2_tctildr.h>

       TSS2_RC Tss2_TctiLdr_GetInfo (constchar *name", TSS2_TCTI_INFO **info);

DESCRIPTION

       The Tss2_TctiLdr_GetInfo() function attempts to instantiate a TSS2_TCTI_INFO  structure  appropriate  for
       the  TCTI  library  associated  with  the  provided name.  The TSS2_TCTI_INFO* reference returned by this
       function must be freed by the Tss2_TctiLdr_FreeInfo () function.

       The name parameter is a C string. If this string is NULL then the library will select a default TCTI  for
       the  caller.  This  is  the  same  TCTI  library  that will be used to initialize the context returned by
       Tss2_TctiLdr_Initialize when passed a NULL name.  If non-NULL, the Tss2_TctiLdr_GetInfo () uses the  same
       algorithm  to  map  the string to the name of an installed TCTI library as the Tss2_TctiLdr_Initialize ()
       function.

       The info parameter is a reference to a TSS2_TCTI_INFO*.  The reference returned will be allocated by  the
       function and must be freed by the caller.

RETURN VALUE

       A  successful  call  to  this function will return TSS2_RC_SUCCESS. An unsuccessful call to this function
       will return a response code described below in section ERRORS.

ERRORS

       TSS2_TCTI_RC_MEMORY is returned if memory allocation fails

       TSS2_TCTI_RC_NOT_SUPPORTED is returned when the loader is unable  to  locate  a  TCTI  library  with  the
       provided name

       TSS2_TCTI_RC_IO_ERROR is returned if a failure occurs in the underlying library loading mechanism

       TSS2_TCTI_RC_BAD_REFERENCE is returned if the info parameter is NULL

EXAMPLE

       Example code.

       #include <inttypes.h>
       #include <stdlib.h>
       #include <stdio.h>

       #include <tss2/tss2_tctildr.h>

       TSS2_TCTI_INFO *info = NULL;
       TSS2_RC rc = Tss2_TctiLdr_GetInfo (NULL, &info);
       if (rc != TSS2_RC_SUCCESS) {
           fprintf (stderr, "Initialization of default TCTI context failed with "
                    "response code: 0x%" PRIx32 "0, rc);
           exit (EXIT_FAILURE);
       }

       if (info != NULL) {
           Tss2_TctiLdr_FreeInfo (info);
           info = NULL;
       }

       exit (EXIT_SUCCESS);
