Miscellaneous

The virtual machine provides the following miscellaneous functions.

U_32 EsVMVersion(void)

Returns the major and minor version numbers of the running virtual machine. To extract the major and minor version numbers from the return value:

U_32 versionNumber;

U_16 versionMajor;

U_16 versionMinor;

versionNumber = EsVMVersion();

versionMajor = versionNumber >> 16;

versionMinor = versionNumber & 0xFFFF;

The minor version number should be interpreted as a two-digit decimal number. For example, version 1.21 of the interpreter has minor version 21. Version 1.3 has minor version 30. Both have a major version of 1.

void EsScavenge(EsVMContext vmContext, U_32 bytesRequired)

Causes the scavenger (a part of the garbage collector) to run once.

Smalltalk equivalent: System scavenge

void EsGGC(EsVMContext vmContext, U_32 bytesRequired)

Causes the global garbage collector to run once.

Smalltalk equivalent: System globalGarbageCollect
