question of the usage

[Yan Huang]

Hi,

I am new to Yasm. I am wondering if yasm provides a library interface of 
assembling human-readable assembly instructions into binary code and 
disassembling binary code to human-readable assembly instructions 
(assuming all the tags used in the instructions have already been 
translated to numbers). I am expecting a well-defined APIs to use in my 
own program.

Could anyone help me out? I really appreciate any information.

Thanks,
Yan
