我想了解的區(qū)別memcpy()和memmove()，和我讀的文本memcpy()，而沒(méi)有照顧重疊源和目的地memmove()一樣。但是，當(dāng)我在重疊的存儲(chǔ)塊上執(zhí)行這兩個(gè)功能時(shí)，它們都給出相同的結(jié)果。例如，在memmove()幫助頁(yè)面上采用以下MSDN示例：-有沒(méi)有更好的例子來(lái)了解它的缺點(diǎn)memcpy以及如何memmove解決？// crt_memcpy.c// Illustrate overlapping copy: memmove always handles it correctly; memcpy may handle// it correctly.#include <memory.h>#include <string.h>#include <stdio.h>char str1[7] = "aabbcc";int main( void ){    printf( "The string: %s\n", str1 );    memcpy( str1 + 2, str1, 4 );    printf( "New string: %s\n", str1 );    strcpy_s( str1, sizeof(str1), "aabbcc" );   // reset string    printf( "The string: %s\n", str1 );    memmove( str1 + 2, str1, 4 );    printf( "New string: %s\n", str1 );}輸出：The string: aabbccNew string: aaaabbThe string: aabbccNew string: aaaabb
