CPXMESSAGEBUFSIZE
Maximum size of message buffers managed by the message interface
#define CPXMESSAGEBUFSIZE 1024
The constant CPXMESSAGEBUFSIZE specifies
the maximum length of a string that the routine
CPXXmsgstr/CPXmsgstr
can process. It also specifies the maximum length of a string that CPLEX
will pass to a function registered by
CPXXaddfuncdest/CPXaddfuncdest.
The string length defined by this constant includes
the terminating NUL character. That is, the maximum length
of the string is actually size minus one.
