What are the related functions of yaffs
This article mainly explains the "what are the yaffs-related functions", the content of the explanation is simple and clear, easy to learn and understand, the following please follow the editor's ideas slowly in-depth, together to study and learn "yaffs-related functions" bar!
1.int yaffs_write (int fd, const void * buf, unsigned int nbyte) what if a file needs to be written to more than a chunk? (just write parts not larger than one chunk, what about the rest?)
2.off_t yaffs_lseek (int fd, off_t offset, int whence)
(1) SEEK_SET=0 search location is offset offset
(2) the current position of SEEK_CUR=1 plus offset offset
(3) SEEK_END=2 file length plus offset offset
3. Yaffsfs_Lock (); / / after watching it for a long time, it is originally equivalent to a semaphore and mutually exclusive.
4. What is the specific difference between these two functions?
Int yaffs_rmdir (const char * path)
{
Return yaffsfs_DoUnlink (path,1)
}
Int yaffs_unlink (const char * path)
{
Return yaffsfs_DoUnlink (path,0)
}
5. Change the current state or parent state (I feel the two are just the opposite, and we need test later)
Int yaffs_stat (const char * path, struct yaffs_stat * buf)
{
Return yaffsfs_DoStatOrLStat (path,buf,0)
}
Int yaffs_lstat (const char * path, struct yaffs_stat * buf)
{
Return yaffsfs_DoStatOrLStat (path,buf,1)
}
6. Wouldn't it be more convenient to directly use the conditions without using the do {} while (0) structure?
7.struct yaffs_dirent * yaffs_readdir (yaffs_DIR * dirp)
8.void yaffs_rewinddir (yaffs_DIR * dirp) / / returns the directory one level above
9.int yaffs_DumpDevStruct (const char * path)
