fs_size_t  fs_fwrite (void       *p_src,
                      fs_size_t   size,
                      fs_size_t   nitems,

File	Called from	Code enabled by
`fs_api.c`	Application	`FS_CFG_API_EN` and not `FS_CFG_RD_ONLY_EN`

Write to a file.

Arguments

p_src

Pointer to source buffer.

size

Size of each item to write.

nitems

Number of items to write.

p_file

Pointer to a file.

Returned Value

Number of items written.

Notes/Warnings

The size or nitems is 0, then the file is unchanged and zero is returned.
If the file is buffered and the last operation is input (read), then a call to fs_fsetpos() or fs_fseek()must occur before output (write can be performed unless the end-of-file was encountered.
The file must have been opened in write or update (read/write) mode.
If the file was opened in append mode, all writes are forced to the end-of-file.
