Finding Error Code <strong>Documentation</strong><br />
For a list of <strong>Virtual</strong> <strong>Disk</strong> <strong>API</strong> error codes, see the online reference guide Introduction to the Vix<strong>Disk</strong>Lib <strong>API</strong>:<br />
Windows – C:\Program Files\<strong>VMware</strong>\<strong>VMware</strong> <strong>Virtual</strong> <strong>Disk</strong> Development Kit\doc\intro.html<br />
Linux – /usr/share/doc/vmware-vix-disklib/intro.html<br />
In a Web browser, click the Error Codes link in the upper left frame, and click any link in the lower left frame.<br />
The right‐hand frame displays an alphabetized list of error codes, with explanations.<br />
Association With VIX <strong>API</strong> Errors<br />
The <strong>Virtual</strong> <strong>Disk</strong> <strong>API</strong> shares many errors with the VIX <strong>API</strong>, which explains the VIX prefix. The error codes for<br />
the VIX <strong>API</strong> are likely to be the same, or almost the same as, a comparable release of the VDDK.<br />
For information about the VIX <strong>API</strong>, including its online reference guide to functions and error codes, see the<br />
developer support section of the <strong>VMware</strong> Web site:<br />
https://www.vmware.com/support/developer/vix‐api/index.html<br />
Interpreting Errors Codes<br />
A VIX error is a 64‐bit value. A value of VIX_OK indicates success, but otherwise (if there is an error), several<br />
bit regions in the 64‐bit value might be set. The least significant 16 bits are set to the error code described for<br />
VIX errors. More significant bit fields might be set to other values.<br />
As for the VIX <strong>API</strong>, use the macro VIX_ERROR_CODE(err) to mask off bit fields not used by the VDDK.<br />
Troubleshooting Dynamic Libraries<br />
On Windows, the SSL library is placed in the same directory as other vix<strong>Disk</strong>Lib dynamically loaded libraries.<br />
On Linux, functions that load the libraries libssl.so.0.9.8 and libcrypto.so.0.9.8 do the following:<br />
1 Attempt to load them from the environment’s LD_LIBRARY_PATH location.<br />
2 Next, attempt to load them from the directory where libvix<strong>Disk</strong>Lib.so is located.<br />
3 Next, attempt to load them from the directory where the executable is located.<br />
4 Failing that, exit with an error.<br />
