This new value is lost when you exit this function as you passed clist1 as a pointer. To make sure this works correctly, you need to pass a pointer to a pointer and derefence it during the function. This makes sure if the pointer changes, the calling function will know about it. voi...
realloc in C 编程语言 在C 编程语言中,realloc() 函数可以重新分配已经分配的内存大小,它是 $stdlib.h$ 头文件中的一个函数。realloc() 函数需要两个参数:指向已分配内存的指针和新的内存大小。它返回一个指向新分配内存的指针。下面是函数签名: void *realloc(void *ptr, size_t size); 其中*ptr 参数...

realloccalls mallocin order to use the C++_set_new_modefunction to set the new handler mode. The new handler mode indicates whether, on failure, malloc is to call the new handler routine as set by_set_new_handler. By default, malloc does not call the new handler routine on failure to ...
New size in bytes Remarks Thereallocfunction changes the size of an allocated memory block. Thememblockargument points to the beginning of the memory block. IfmemblockisNULL,reallocbehaves the same way asmallocand allocates a new block ofsizebytes. Ifmemblockis notNULL, it should be a pointer...
char *p=(char *)malloc(10);通过这句话给p分配了空间后, 并没有将其进行输出化, 所以这段内存中的内容是不确定了,而用strlen()求一个字符串的长度时, 只有遇到字符串结束符'\0'才会结束, 所以长度就不确定了...
