Resumes VMX non-root operation by using the current virtual machine control structure (VMCS).
unsigned char __vmx_vmresume(
void);
Return Value

Meaning |
|---|---|
0 |
The operation succeeded. |
1 |
The operation failed with extended status available in the VM-instruction error field of the current VMCS. |
2 |
The operation failed without status available. |
Remarks
An application can perform a VM-enter operation by using either the __vmx_vmlaunch or __vmx_vmresume function. The __vmx_vmlaunch function can be used only with a VMCS whose launch state is Clear, and the __vmx_vmresume function can be used only with a VMCS whose launch state is Launched. Consequently, use the __vmx_vmclear function to set the launch state of a VMCS to Clear, and then use the __vmx_vmlaunch function for your first VM-enter operation and the __vmx_vmresume function for subsequent VM-enter operations.
The __vmx_vmresume function is equivalent to the VMRESUME machine instruction. This function supports the interaction of a host's virtual machine monitor with a guest operating system and its applications.
