Print one attribute and value to FP.

Complete string with '\t' and '\n' is written to buffer before printing to avoid issues when running with multiple threads.

Todo:

• This function should print flattened lists.

Parameters

fp	to output to.
vp	to print.

Returns

• >=0 on success
• <0 on error
