The FILE_MAILSLOT_SET_INFORMATION structure is used to set a value on a mailslot.

Syntax

  PLARGE_INTEGER ReadTimeout;
} FILE_MAILSLOT_SET_INFORMATION, *PFILE_MAILSLOT_SET_INFORMATION;

Members

ReadTimeout

The time, in milliseconds, that a read operation can wait for a message to be written to the mailslot before a time-out occurs.
