26 | * Try to keep one section per platform, compiler and architecture, otherwise, |
27 | * if an existing section is reused for a different one and later on the |
28 | * original is adjusted, probably the piggybacking one can be adversely |
29 | * changed. |
30 | * |
31 | * In order to differentiate between platforms/compilers/architectures use |
32 | * only compiler built in predefined preprocessor symbols. |
33 | * |
34 | * curl_off_t |
35 | * ---------- |
36 | * |
37 | * For any given platform/compiler curl_off_t must be typedef'ed to a 64-bit |
38 | * wide signed integral data type. The width of this data type must remain |
39 | * constant and independent of any possible large file support settings. |
40 | * |
41 | * As an exception to the above, curl_off_t shall be typedef'ed to a 32-bit |
42 | * wide signed integral data type if there is no 64-bit type. |
43 | * |
44 | * As a general rule, curl_off_t shall not be mapped to off_t. This rule shall |
45 | * only be violated if off_t is the only 64-bit data type available and the |
46 | * size of off_t is independent of large file support settings. Keep your |
47 | * build on the safe side avoiding an off_t gating. If you have a 64-bit |
48 | * off_t then take for sure that another 64-bit data type exists, dig deeper |
49 | * and you will find it. |
