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);
