Files
attrib = FS_ENTRY_ATTRIB_RD;
FSEntry_AttribSet(“path_name”, <-- pointer to full path name
attrib, <-- attributes
&err); <-- return error
FS_ENTRY_ATTRIB_RD
Entry is readable.
FS_ENTRY_ATTRIB_WR
Entry is writable.
FS_ENTRY_ATTRIB_HIDDEN
Entry is hidden from user-level processes.
If a flag is clear (not OR’d in), then that attribute will be clear. In the example above, the
entry will be made read-only (i.e., not writable) and will be visible (i.e., not hidden) since
the WR and HIDDEN flags are not set in attrib . Since there is no way to make files
write-only (i.e., not readable), the RD flag should always be set.
7-2-2 CREATING NEW FILES AND DIRECTORIES
A new file can be created using FSFile_Open() or fs_fopen() , if opened in write or
append mode. There are a few other ways that new files can be created (most of which also
apply to new directories).
The simplest is the FSEntry_Create() function, which just makes a new file or directory:
FSEntry_Create(“\\file.txt”,
FS_ENTRY_TYPE_FILE,
DEF_NO,
&err);
<--
<--
<--
<--
file name
means entry will be a file
DEF_NO means creation NOT exclusive
return error
If the second argument, entry_type , is FS_ENTRY_TYPE_DIR the new entry will be a
directory. The third argument, excl , indicates whether the creation should be exclusive. If it
is exclusive ( excl is DEF_YES ), nothing will happen if the file already exists. Otherwise, the
file currently specified by the file name will be deleted and a new empty file with that name
created.
