// Minimal stdint.h essentials, loosely based on Paul Hsieh's pstdint.h
|
||
|
|
// See http://www.azillionmonkeys.com/qed/pstdint.h for reference.
|
||
|
|
// This adds only the xint*_t types, xINT*_C() macros, and xINT*_MAX defines for older versions of visual studio.
|
||
|
|
// Might want to use the full pstdint.h instead if needed to support older compilers.
