VMMCall Out_Mono_String

Writes the specified null-terminated string to the secondary display. If the string contains register placeholders, Out_Mono_String replaces these with the actual register values (in hexadecimal), or the symbolic label nearest to the specified addresses. Uses all registers and flags.

No return value.

String

Points to a null-terminated string specifying the message to write to the debugging device. Out_Mono_String uses the lods instruction to process characters in the string, so the DS register must specify the correct segment selector for the string.

The string can contain one or more placeholders having the following forms:

Placeholder Description

#register Displays the current value of the specified register. For example, the service replaces #AX with the value of the AX register. The register must not be the name of a segment register.

?register Displays the label nearest the address specified by the registers. For example, the service replaces ?EAX with the VMM code segment label nearest the address in the EAX register. The register must not be the name of a segment register.

?register:register Displays the label nearest the address specified by the registers. For example, the service replaces ?AX:EBX with the label in the segment specified by the AX register that is nearest to the address in the EBX register. The register must not be the name of a segment register.

Placeholder	Description
#register	Displays the current value of the specified register. For example, the service replaces #AX with the value of the AX register. The register must not be the name of a segment register.
?register	Displays the label nearest the address specified by the registers. For example, the service replaces ?EAX with the VMM code segment label nearest the address in the EAX register. The register must not be the name of a segment register.
?register:register	Displays the label nearest the address specified by the registers. For example, the service replaces ?AX:EBX with the label in the segment specified by the AX register that is nearest to the address in the EBX register. The register must not be the name of a segment register.

This service has no effect in the retail version of Windows. It is intended to be used with the debugging version.
