Manages circular buffers by wrapping indices around and doing the equivalent of memset() and memcpy() on circular buffers or from linear buffers to circular buffers. generic_buffer.c / generic_buffer.h A generic buffer is a structure that contains a buffer (usually used as a string, otherwise...
Thread safe, no memory allocation, and raises no exceptions. cpu_features is suitable for implementing fundamental libc functions like malloc, memcpy, and memcmp. Unit tested. 编译: mkdir build&&cdbuild cmake ..&&make -j ./build/list_cpu_features#列出本机CPU参数"arch : x86brand : Intel(R...
by using 64bit ops, not 32bit. With clang-4+ memcpy_s is now as fast as memcpy native, with gcc only 77% slower. Added more benchmarks and improved the timing. - Made the unsafe functions snprintf_s, vsnprintf_s, snwprintf_s, vsnwprintf_s ...
