linux中如何查看glibc内存分配情况

在Linux中，可以使用工具如malloc_info、mtrace、valgrind、gdb等来查看glibc内存分配情况。

例如，可以使用mallinfo函数来查看glibc内存分配情况，示例代码如下：

#include  #include   int main() {     struct mallinfo mi = mallinfo();     printf("Total non-mmapped bytes (arena): %dn", mi.arena);     printf("# of free chunks (ordblks): %dn", mi.ordblks);     printf("# of fastbin blocks (smblks): %dn", mi.smblks);     printf("# of mmapped regions (hblks): %dn", mi.hblks);     printf("Space in mmapped regions (hblkhd): %dn", mi.hblkhd);     printf("Maximum total allocated space (usmblks): %dn", mi.usmblks);     printf("Free space (fsmblks): %dn", mi.fsmblks);     printf("Total allocated space (uordblks): %dn", mi.uordblks);     printf("Total free space (fordblks): %dn", mi.fordblks);     printf("Topmost releasable block (keepcost): %dn", mi.keepcost);          return 0; } 

编译并运行上述代码，即可查看glibc内存分配情况。
