Error Codes by Number in the CPLEX Callable Library (C API)
This numerically sorted list of CPLEX error codes links to the reference documentation of each code.
This list of error codes, sorted numerically, links to fuller documentation of error codes in the reference manual of the Callable Library (C API). In addition, Error Code Symbols in the CPLEX Callable Library (C API) lists error codes sorted alphabetically by symbolic name with links to the same documentation of each such code. In other words, you can look up errors by number or by symbol.
