Results for “atomic write”
Small, practical examples. Search by task or narrow things down below.
Assign a bit from a Boolean state
Arduino / C: bitWrite accepts a bit position and a zero or nonzero value.
Arduino / C✓ Tested
Increment a shared counter safely
C++: Atomic increments prevent lost updates when two threads change the same counter.
C++✓ Tested
Replace bytes at a known position in a binary file
C: Open in update mode and seek before writing a fixed-size replacement.
C✓ Tested
Serialize a 16-bit integer in big-endian order
C: Explicit shifts make a byte format independent of the CPU’s native byte order.
C✓ Tested
Serialize an object to JSON
Serialize a small anonymous C# object with System.Text.Json.
C#✓ Tested
Turn on the built-in LED
Configure the Uno’s LED pin as an output and drive it high.
LED_BUILTIN✓ Tested
Append text to a file
Open a C++ stream in append mode and verify the write.
C++✓ Tested
Calculate changes between successive readings
C++: adjacent_difference keeps the first value and then writes each difference from its predecessor.
C++✓ Tested
Calculate cumulative totals
C++: partial_sum writes the sum of each input prefix to the output sequence.
C++✓ Tested
Check whether a file is already sorted
Linux Commands: Use sort -C for a quiet status check that does not rewrite the file.
Linux Commands✓ Tested
Collect two independent background results
Bash Scripts: Write each job’s output separately and wait for both before combining results.
Bash Scripts✓ Tested
Compute a generated column
Store inputs and derive a value from them.
