# [DESCRIPTION](#DESCRIPTION)

**TPMLIB\_SetDebugFD()** allows to set the file descriptor to send the debug output to.

**TPMLIB\_SetDebugLevel()** allows to set the debug level. Only debug levels greater than 1 will produce output. The indentation level of a line will determine whether it is printed. Lines with 0 indentation will be printed at debug level 1, 1 space of indentation at debug level 2 and so on.

**TPMLIB\_SetDebugPrefix()** allows to set a prefix that is to be printed in front of every line of debugging output. The prefix can be used for further indentation.
