strtol (string to long) or strtoul (string to unsigned long) will do the job, as GGrundy says.  Be sure to set the last parameter to 16 so that it will know you are converting hexidecimal digits.  For instance:

char* pEnd;
char szHexText="0102A53F";

unsigned long nBinaryValue= strtoul( szHexText, &pEnd, 16 );
