=head1 NAME
TPMLIB_MainInit - Initialize the TPM
TPMLIB_Terminate - Terminate the TPM
=head1 LIBRARY
TPM library (libtpms, -ltpms)
=head1 SYNOPSIS
B<#include <libtpms/tpm_types.h>>
B<#include <libtpms/tpm_library.h>>
B<#include <libtpms/tpm_error.h>>
B<TPM_RESULT TPMLIB_MainInit(void);>
B<TPM_RESULT TPMLIB_Terminate(void);>
=head1 DESCRIPTION
The B<TPMLIB_MainInit()> and B<TPMLIB_Terminate()> functions are used
to initialize and terminate the TPM respectively. The B<TPMLIB_MainInit()>
function must be called before the TPM processes any TPM command.
The B<TPMLIB_Terminate()> function is called to free all the internal
resources (memory allocations) the TPM has used and must be called after
the last TPM command was processed by the TPM. The B<TPMLIB_MainInit()>
function can then be called again.
Use B<TPMLIB_RegisterCallbacks()> to set callback functions for
initialization and writing and restoring the internal state in a
portable format.
=head1 ERRORS
=over 4
=item B<TPM_SUCCESS>
The function completed successfully.
=item B<TPM_FAIL>
General failure.
=back
For a complete list of TPM error codes please consult the include file
B<libtpms/tpm_error.h>
=head1 EXAMPLE
#include <stdio.h>
#include <libtpms/tpm_types.h>
#include <libtpms/tpm_library.h>
#include <libtpms/tpm_error.h>
int main(void) {
TPM_RESULT res;
unsigned char *respbuffer = NULL;
uint32_t resp_size = 0;
uint32_t respbufsize = 0;
unsigned char *command;
uint32_t command_size;
[...]
if (TPMLIB_MainInit() != TPM_SUCCESS) {
fprintf(stderr, "Could not start the TPM.\n");
return 1;
}
[...]
/* build TPM command */
[...]
res = TPMLIB_Process(&respbuffer, &resp_size,
&respbufsize,
command, command_size);
[...]
TPMLIB_Terminate();
return 0;
}
