Members

shi502_netname

Pointer to a Unicode string specifying the name of a shared resource. Calls to the NetShareSetInfo function ignore this member.

shi502_type

A combination of values that specify the type of share. Calls to the NetShareSetInfo function ignore this member.

One of the following values may be specified. You can isolate these values by using the STYPE_MASK value.

Value Meaning
STYPE_DISKTREE
 Disk Drive.
STYPE_PRINTQ
 Print Queue.
STYPE_DEVICE
 Communication device.
STYPE_IPC
 Interprocess communication (IPC).
 

In addition, one or both of the following values may be specified.

Value Meaning
STYPE_SPECIAL
 Special share reserved for interprocess communication (IPC$) or remote administration of the server (ADMIN$). Can also refer to administrative shares such as C$, D$, E$, and so forth. For more information, see the network share functions.
STYPE_TEMPORARY
 A temporary share.

shi502_remark

Pointer to a Unicode string specifying an optional comment about the shared resource.

shi502_permissions

Specifies a DWORD value that indicates the shared resource's permissions for servers running with share-level security. This member is ignored on a server running user-level security. This member can be any of the following values. Calls to the NetShareSetInfo function ignore this member.

Note that Windows does not support share-level security. For more information about controlling access to securable objects, see Access Control, Privileges, and Securable Objects.

Value Meaning
ACCESS_READ
 Permission to read data from a resource and, by default, to execute the resource.
ACCESS_WRITE
 Permission to write data to the resource.
ACCESS_CREATE
 Permission to create an instance of the resource (such as a file); data can be written to the resource as the resource is created.
ACCESS_EXEC
 Permission to execute the resource.
ACCESS_DELETE
 Permission to delete the resource.
ACCESS_ATRIB
 Permission to modify the resource's attributes (such as the date and time when a file was last modified).
ACCESS_PERM
 Permission to modify the permissions (read, write, create, execute, and delete) assigned to a resource for a user or application.
ACCESS_ALL
 Permission to read, write, create, execute, and delete resources, and to modify their attributes and permissions.

shi502_max_uses

Specifies a DWORD value that indicates the maximum number of concurrent connections that the shared resource can accommodate. The number of connections is unlimited if the value specified in this member is –1.

shi502_current_uses

Specifies a DWORD value that indicates the number of current connections to the resource. Calls to the NetShareSetInfo function ignore this member.

shi502_path

Pointer to a Unicode string that contains the local path for the shared resource. For disks, this member is the path being shared. For print queues, this member is the name of the print queue being shared. Calls to the NetShareSetInfo function ignore this member.

shi502_passwd

Pointer to a Unicode string that specifies the share's password (when the server is running with share-level security). If the server is running with user-level security, this member is ignored. Note that Windows does not support share-level security.

This member can be no longer than SHPWLEN+1 bytes (including a terminating null character). Calls to the NetShareSetInfo function ignore this member.

shi502_reserved

Reserved; must be zero. Calls to the NetShareSetInfo function ignore this member.

shi502_security_descriptor

Specifies the SECURITY_DESCRIPTOR associated with this share.
