Important Notice

The pages on this site contain documentation for very old MS-DOS software, purely for historical purposes. If you're looking for up-to-date documentation, particularly for programming, you should not rely on the information found here, as it will be woefully out of date.

VxDcall DOSMGR_Enable_Indos_Polling
 
The DOSMGR_Enable_Indos_Polling service enables the INDOS polling for the
the Windows session. This allows TSR drivers that hook Interrupt 21h and
claim the critical section by setting the internal MS-DOS INDOS flag to
continue to operate normally.
 
This service is intended for use by the virtual DOSNET device so that it can
enable polling if the installed network requires it. The virtual device must
not call this service during a Sys_Critical_Init message.
 
This service has no parameters.
 
Return Value
 
The carry flag is clear if INDOS polling is enabled. Otherwise, the carry
flag is set to indicate polling was already enabled.
 
Comments
 
Enabling INDOS polling has a severe impact on overall system performance.
 
This service overrides the INDOSPOLLING value specified in the SYSTEM.INI
file. Since the virtual MS-DOS manager evaluates the SYSTEM.INI file during
the Init_Complete message, a virtual device must call this service during
the Device_Init message.
