Shareable Data Attributes

These attributes determine whether all instances of the program can share a READWRITE data segment:

SHARED

One copy of the data segment is loaded and shared among all processes accessing the module (default for dynamic-link libraries).
NONSHARED
The segment cannot be shared, and must be loaded separately for each process (default for applications).

These attributes refer to non-initialized global data. Under OS/2, this field is ignored if READONLY is specified, since READONLY data segments are always shared.
