Inline function is like a macro definition. When it was be called in another function, the control right will not be changed to this function. The compiler will just replace the line of inline function with the actual content of the function. We use inline function to eliminate the cost of...
The calloc() function in C stands for contiguous allocation. It is used to dynamically allocate memory for an array of elements, initialize them to zero, and then return a pointer to the memory. Syntax void* calloc(size_t num, size_t size); Parameters num: This represents the number of...
C library - calloc() function - The C stdlib library calloc() function is used to allocates the requested memory and returns a pointer to it. It reserves a block of memory for array of objects and initialize all bytes in the allocated storage to zero.

C 库函数 - calloc() C 标准库 - <stdlib.h> 描述 C 库函数 void *calloc(size_t nitems, size_t size) 分配所需的内存空间,并返回一个指向它的指针。malloc 和 calloc 之间的不同点是,malloc 不会设置内存为零,而 calloc 会设置分配的内存为零。 注意:calloc

The calloc function allocates storage space for an array of num elements, each of length size bytes. Each element is initialized to 0. calloc sets errno to ENOMEM if a memory allocation fails or if the amount of memory requested exceeds _HEAP_MAXREQ. For information on this and other error...
