Adds man:strdupa[3] and man:strndupa[3] functions, which allocate memory for a copy of a string on the stack using man:alloca[3]. This provides a convenient alternative to man:strdup[3] and man:strndup[3] for temporary string copies that are automatically freed when the function returns. gitref:b2e649a0b98d[repository=src]. -Adds C23 `<stdbit.h>` header with bit manipulation functions like `stdc_bit_ceil()`, `stdc_bit_width()`, and `stdc_count_ones()`. This provides standard bit operations for C programs. -gitref:275c11b7ccff[repository=src]. - -The C23 trigonometric functions from the `*pi` family (acospi, acospif etc.) have beed exposed in <math.h>. This provides standard-conforming APIs for applications using these functions. -gitref:104488641aca[repository=src]. - -The C23 `memalignment()` function has been added to libc, allowing programs to compute pointer alignment. A man page has been included. -gitref:24ea81047de7[repository=src]. - The SONAME of libzfs and libzpool have been bumped to libzfs7 and libzpool7 due to ABI-breaking changes, requiring recompilation of dependent applications. gitref:5b2489caf266[repository=src]. Adds libuvmem, a userland port of the man:vmem[9] kernel memory allocator, providing a similar interface for userland applications. gitref:3ae14e8f332f[repository=src]. +Partial support for the C23 version of the C Programming language is now available. It will continue to evolve, with complete support anticipated for FreeBSD 16. New features include the `<stdbit.h>` header, the man:memalignment[3] function, updates to the `<limits.h>` and `<stdint.h>` headers including the `_WIDTH` macros and `char8_t`, as well as various other extensions. +gitref:275c11b7ccff[repository=src], +gitref:104488641aca[repository=src], +gitref:24ea81047de7[repository=src], +gitref:5656d0f7453e[repository=src], +gitref:72609bb2bb25[repository=src], +gitref:ff50ace5fe0e[repository=src], +gitref:cbad54ba46e6[repository=src], +gitref:6fc280810ead[repository=src]. + [[cloud]] == Cloud Supporthome | help
