I am new to bitcoin mining.
I want to give unique number to the cpuminer.
How can I do this ? ( I set this unique nonce myself. )
Also for this nonce, I need block header parameters in the moment.
How can I get this parameters from cpuminer ?
My last question is how to integrate these components with my unique nonce and get the block's hash ? ( That is, how do I import these parameters as input to the SHA-256 function ? )

I am happy with any guidance.
