WebJul 30, 2024 · 2 Answers Sorted by: 1 When you compile with a 32-bit toolchain, the members of struct timeval are 32 bit, and when you compile with a 64-bit toolchain, they're 64 bit. That means that the values you provided are automatically converted to the appropriate type by the compiler, and the data you passed it is of the right size.

WebMar 18, 2013 · It runs on systems where the maximum data size is 32 bits and ones where it could be 128 bits or more. For 64-bit systems, you want a 64-bit time_t and related types (so that you don't run out of time in 2038), but the systems that C was originally written for couldn't (easily) address data types that large. – rra Mar 18, 2013 at 6:02 Add a comment WebAug 10, 2024 · StructureFieldBitSize.cpp. // I've needed a constexpr way to get a size of the bit fields in struct (i.e. number of bits). // so constexpr functions could only use a single … chimney sweeps west bend wi https://kdaainc.com

[PATCH] usb: misc: usbtest: Remove timeval usage

WebThe two ioctls are necessary to maintain the 32 bit and 64 bit userspace compatibility with a 64/32 bit kernel. Change unsigned to __u32 types for a definitive userspace interface. This is in accordance with the psABI that the unsigned type is always 32 bits. Also use motonic timer instead of real time to ensure positive delta values. http://andersk.mit.edu/gitweb/openssh.git/blobdiff/610e8ff500c68603d8a6262f285d0456af810aae..7a9c7a0baf3a3ffd69fe5ed6ed9be2b35c23de92:/defines.h
