pls tell me what is the meaning of return -2 in c?
these are the statements in a code
if(Plc_Active_Fl==0)return 0;
if(ENGRAVING_ON_FL==1)return -2;

in the above statements, function is checking PLC_active_fl flag if its 0 then function returns back 0 and if Engraving_On_fl is 1 then it returns a value -2.
usually -ve vaules are for showing errors. positive and 0 are for OK status.

but the value -2 is not used in program,
then why -2 only is returned to the main program?

I cannot help you with that.
