Gutenprint Discontinues macOS Support

As of July 7, 2024 the Gutenprint project has formally deprecated MacOS support. This means that no further MacOS-compatible binaries will be produced. Gutenprint has not had an active MacOS maintainer for over three years, and the remaining developers lack the technical ability to produce MacOS binaries, much less undertake the substantial amount of work necessary to produce, test, and support binaries on newer (post-Mojave/10.14) MacOS releases.

How to Use Snprintf

news.ycombinator.com Max Bernstein 2025-11-12 00:53:39

The sprintf family of functions ( sprintf , snprintf , vsnprintf , …) have this little-known feature to what size your buffer should be. In cases where you don’t have a fixed upper bound, this is really useful. For example: int size = snprintf ( /*str=*/ NULL , /*size=*/ 0 , "%d: %s" , some_int , some_c_str ); if ( size < 0 ) abort (); int size_with_nul = size + 1 ; char * buf = malloc ( size_with_nul ); if ( buf == NULL ) abort (); int result = snprintf ( /*str=*/ buf , /*size=*/ size_with_nu
