copies characters from 'src' to 'dest', copying is stopped when either the 'stop' character is reached or after 'cnt' characters have been copied, whichever comes first.

| void SCIPprintSysError | ( | const char * | message | ) |
prints an error message containing of the given string followed by a string describing the current system error; prefers to use the strerror_r method, which is threadsafe; on systems where this method does not exist, NO_STRERROR_R should be defined (see INSTALL), in this case, srerror is used which is not guaranteed to be threadsafe (on SUN-systems, it actually is)

| message | first part of the error message, e.g. the filename |
