converting an unsigned char to an int?

hi i have s specific string of 8 bytes in my program which i have collected using the following code

CPP / C++ / C Code:



	unsigned char _1,_2,_3,_4,_5,_6,_7,_8;


infile.read (&_1,sizeof (_1)) ;		
infile.read (&_2,sizeof (_2)) ;
infile.read (&_3,sizeof (_3)) ;		
infile.read (&_4,sizeof (_4)) ;
infile.read (&_5,sizeof (_5)) ;		
infile.read (&_6,sizeof (_6)) ;
infile.read (&_7,sizeof (_7)) ;		
infile.read (&_8,sizeof (_8)) ;

char unixtime [9]; 

unixtime[0]=_1;
unixtime[1]=_2;
unixtime[2]=_3;
unixtime[3]=_4;
unixtime[4]=_5;
unixtime[5]=_6;
unixtime[6]=_7;
unixtime[7]=_8;
unixtime[8]='/0';

when i print out unixtime i get 45d732f6 which is ok but i want to store this value in an int called uTim. I also want to proceed my string with '0x' so that it is recognised as a string of hex. In an ideal world something like

CPP / C++ / C Code:

int uTim = 0x45d732f6;

is it possible to convert unixtime into and int?

thank you

If you are looking to convert a string to an int/long value, you can always use strtol. strtol will allow you to specify a base to use in the conversion so that you do not have to worry about prepending the 0x to your existing data.
