DESCRIPTION

28       The TPM_Malloc() function is used to allocate a buffer of the given
29       size.  The allocated buffer will be returned in the buffer parameter.
30
31       The TPM_Realloc() function is used to resize a buffer. The new size of
32       the buffer is given in the size parameter. The reallocated buffer will
33       contain the data from the original buffer.
34
35       Both functions have the restriction that the buffer they can allocate
36       is limited to TPM_ALLOC_MAX (64k) bytes. This size is sufficient for
37       all buffers needed by the TPM.
38
39       Upon successful completion, the functions return TPM_SUCCESS. In case
40       the requested buffer exceeds the limit, TPM_SIZE will be returned. See
41       further possible error codes below.
42
43       The TPM_Free() function frees the memory previously allocated using
44       either TPM_Malloc() or TPM_Realloc().
45

ERRORS

47       TPM_SUCCESS
48           The function completed successfully.
49
50       TPM_SIZE
51           The size of the requested buffer exceeds the limit or the system is
52           out of memory.
53
54       TPM_FAIL
55           Requested buffer is of size 0.
