FSResult FS_ARCHIVE_PROC_FUNC(
FSFile *p_file,
FSCommandType command /* = FS_COMMAND_WRITEFILE */);
Operating specifications for the archive command FS_COMMAND_WRITEFILE are shown below:
arg.readfile that is stored in p_file.nitro/fs/file.h as shown below:
typedef struct
{
const void *src;
u32 len_org;
u32 len;
} FSWriteFileInfo;
| Arguments | Content |
|---|---|
src |
The memory address for the source data to be written to a file. |
len_org |
Indicates the size of data to write (bytes), using the specified value as-is. |
len |
Specifies the size of data to be written (bytes), using a value that is adjusted by the file size at the time that the command is called. |
p_file is a handle that always stores file information in prop.file. Based on p_file's prop.file argument, the command makes the following settings:
len bytes of data from memory indicated by src to an archive offset position that is indicated by prop.file.pos.len to prop.file.pos.len is adjusted from the specified value, taking prop.file.bottom into consideration. If you want to run a special process when a write exceeds the file size, you can use the original value that is stored in len_org.
len bytes from src to the base offset position indicated by prop.file.pos. It then adds len to prop.file.pos.FS_RESULT_SUCCESS is returned by the command, it means that the transfer process for len bytes completed properly. When anything else is returned by the command, it means that transfer failed due to some error.FSArchive, FS_ARCHIVE_PROC_FUNC, FS_COMMAND_*, FS_SetArchiveProc
