Uclinux uses a structure called cpumask_t to hold information about each CPU. The definition is in Include/linux/cpumask.h, as follows: typedef struct {Declare_bitmap (bits, Nr_cpus);} cpumask_t; Where Declare_bitmap is defined as: #define BITS_TO_LONGS(bits) / (((bits)+BITS_PER_LONG-1)/BITS_PER_LONG) #define DECLARE_BITMAP(name,bits) / unsigned long name[BITS_TO_LONGS(bits)] So for bf561, the definition of cpumask_t is equivalent to: typedef struct {unsigned long bits[1];} cpumask_t; The

Cat (apr_array_header_t *dst,const apr_array_header_t *src) The function adds the array src to the end of the array DST. The function first checks whether the current idle cell can tolerate the SRC array, the concept of which is not to accommodate the nalloc element in SRC, but merely to accommodate the nelts non-idle unit in SRC, not including the Nalloc-nelts idle unit, so the function needs to be compa

Introduction The shutil module provides advanced operations for a large number of files. Especially for file copying and deletion, the main functions are directory and file operations and compression operations. For operations on a single file, see the OS module. Note that even higher-level file replication functions (shutil. copy (), shutil. copy2 () cannot copy the metadata of all files. This means that on the POSIX platform, the file owner, group, and access control list will be lost. In Mac
