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