To allocate memory dynamically, library functions aremalloc(),calloc(),realloc()andfree()are used. These functions are defined in the<stdlib.h>header file. C malloc() The name "malloc" stands for memory allocation. Themalloc()function reserves a block of memory of the specified number of by...
动态内存分配(Dynamic memory allocation) 相关知识点: 试题来源: 解析 答:尽管不像非嵌入式计算机那么常见,嵌入式系统还是有从堆(heap)中动态分配内存的过程的。那么嵌入式系统中,动态分配内存可能发生的问题是什么? 这里,我期望应试者能提到内存碎片,碎片收集的问题,变量的持行时间等等。这个主题已经在ESP杂志中被...
