同所有边界检查函数,memcpy_s,仅若实现定义__STDC_LIB_EXT1__且用户在包含<string.h>前定义__STDC_WANT_LIB_EXT1__为整数常量 1 才保证可用。 参数 dest-指向复制目标对象的指针 destsz-目标中要修改的最大字节数(典型地为目标对象的大小) src-指向复制来源对象的指针 ...
在缓冲区之间复制字节。 这些函数的版本是memcpy、wmemcpy,具有安全性增强功能,如CRT 中的安全功能中所述。 语法 C errno_tmemcpy_s(void*dest,size_tdestSize,constvoid*src,size_tcount );errno_twmemcpy_s(wchar_t*dest,size_tdestSize,constwchar_t*src,size_tcount ); ...
, dest[4]; memcpy(dest, source, sizeof dest); for(size_t n = 0; n < sizeof dest; ++n) putchar(dest[n]); // 设置分配的内存的有效类型为 int int *p = malloc(3*sizeof(int)); // 分配的内存无有效类型 int arr[3] = {1,2,3}; memcpy(p,arr,3*sizeof(int)); // 分配的...
