| 28 | * Determine which string to integral data type conversion function we use
|
---|
| 29 | * to implement string conversion to our curl_off_t integral data type.
|
---|
| 30 | *
|
---|
| 31 | * Notice that curl_off_t might be 64 or 32 bit wide, and that it might use
|
---|
| 32 | * an underlying data type which might be 'long', 'int64_t', 'long long' or
|
---|
| 33 | * '__int64' and more remotely other data types.
|
---|
| 34 | *
|
---|
| 35 | * On systems where the size of curl_off_t is greater than the size of 'long'
|
---|
| 36 | * the conversion function to use is strtoll() if it is available, otherwise,
|
---|
| 37 | * we emulate its functionality with our own clone.
|
---|
| 38 | *
|
---|
| 39 | * On systems where the size of curl_off_t is smaller or equal than the size
|
---|
| 40 | * of 'long' the conversion function to use is strtol().
