An attempt was made to query an external function in DLL dll-name, but either the function name was null, or the length of the function name was negative.
The request is ignored.
If this was a C dllqueryfn() or dlsym() request and the _EDC_DLL_DIAG environment variable was not set to QUIET, the error message was sent to the Language Environment® message file. Other DLL diagnostic options, such as issuing ctrace(), signaling a condition, and turning off _EDC_DLL_DIAG diagnostics, were available through the _EDC_DLL_DIAG environment variable.
If this was an explicit C dlsym() request, this error could also be returned to the caller through a subsequent call to the C dlerror() function.
A CEEDLLF DLL failure control block was populated with further DLL error diagnostics.
Ensure that the function name and length are specified correctly on the DLL Query Function request.
