Files
Attrib contains the file attributes (see section 7-2-1 “File and Directory Attributes” on
page 104).
Size is the size of the file, in octets.
DateTimeCreate is the creation timestamp of the file.
DateAccess is the access timestamp (date only) of the file.
DateTimeWr is the last write (or modification) timestamp of the file.
BlkCnt is the number of blocks allocated to the file. For a FAT file system, this is the
number of clusters occupied by the file data.
BlkSize is the size of each block allocated in octets. For a FAT file system, this is the
size of a cluster.
DateTimeCreate , DateAccess and DateTimeWr are structures of type CLK_TS_SEC .
7-1-3 CONFIGURING A FILE BUFFER
The file module has functions to assign and flush a file buffer that are equivalents to POSIX
API functions; the primary difference is the advantage of valuable return error codes to the
application.
File Module Function
void FSFile_BufAssign (FS_FILE *p_file,
void *p_buf,
FS_FLAGS mode,
CPU_SIZE_T size,
FS_ERR *p_err);
POSIX API Equivalent
int fs_setvbuf (FS_FILE *stream,
char *buf,
int mode,
fs_size_t size);
void FSFile_BufFlush (FS_FILE
FS_ERR
*p_file,
*p_err);
int fs_fflush (FS_FILE
*stream);
For more information about and an example of configuring a file buffer, see section 6-3-3
“Configuring a File Buffer” on page 91.
