◆ loadImage() [1/2]

void SystemInterpreter::loadImage ( char **  imageBuffer,
size_t *  imageSize 
)
static

Load the base image into storage.

Parameters
imageBufferreturned start of the image
imageSizereturned size of the image
Remarks
We pass null to primitiveSearchName(), which has the effect of the Windows API SearchPath() being called with null for the path. When SearchPath is called with null for the path, and there is no path informtion in the file name, the first directory searched is the directory in which the application (rexx.exe) image is located.

Since, on Windows, the base image (rexx.img) is always located in the same directory as rexx.exe, this results in the image being found faster. For development, it prevents the wrong base image being picked up during a compile.

If the image is not found in the application image's directory, the regular executable search, which searches the path, is performed.
