NAME

       TPMLIB_SetBufferSize  - Set the TPM's I/O buffer size

LIBRARY

       TPM library (libtpms, -ltpms)

SYNOPSIS

       #include <libtpms/tpm_library.h>

       uint32_t TPMLIB_SetBufferSize(uint32_t, uint32_t *, uint32_t *);

DESCRIPTION

       The TPMLIB_SetBufferSize() function sets the size of the buffer the TPM can use for input
       and output and that it advertises to users.  It also allows a user to get the minimum and
       maximum supported buffer size.

       If 0 is given on input, the currently used buffer size is returned.  Any other number will
       try to change the buffer size. The returned size may be smaller than the requested one, if
       the requested one was above a maximum. The returned size may be larger than the requested
       one, if the requested one was below a minimum.

       This function must be called after TPMLIB_ChooseTPMVersion() has been called. It should
       not be called after TPMLIB_MainInit() has been called but can again be called once
       TPMLIB_Terminate() has been called.
