29 * Determine which string to integral data type conversion function we use
30 * to implement string conversion to our curl_off_t integral data type.
32 * Notice that curl_off_t might be 64 or 32 bit wide, and that it might use
33 * an undelying data type which might be 'long', 'int64_t', 'long long' or
34 * '__int64' and more remotely other data types.
36 * On systems where the size of curl_off_t is greater than the size of 'long'
37 * the conversion funtion to use is strtoll() if it is available, otherwise,
38 * we emulate its functionality with our own clone.
40 * On systems where the size of curl_off_t is smaller or equal than the size
41 * of 'long' the conversion funtion to use is strtol().
