 This function allocates a file descriptor to the calling task, for the file identified by its absolute "pathname". 
 If several tasks try to open the same file, each task obtains a private file descriptor.
 The semantic is similar to the UNIX open() function, but the UNIX oflags and the UNIX access rights are not supported. 
-If the file does not exist in the specified directory, it is created.
+The two following flags can be ''ored'' in the '''flags''' argument:
+ * O_RDONLY : the file will accessed as read-only. Default value is read/write.
+ * O_CREATE  : the file will be created if it does not exist on the file system. Default value is no creation.
 If the specified directory does not exist, an error is returned.
