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