Redirect errors and warnings

By default, esql directs error and warning messages it generates to standard output. If you want the errors and warnings to be put into a file, use the -log option with the file name.

For example, the following esql command compiles the program demo1.ec and sends the errors to the err.out file: 
esql -log err.out -o demorun demo1.ec

This option only affects the error warnings that the Informix® ESQL/C preprocessor generates. The warnings from the compile and link stages still go to the standard error output, which is stderr on UNIX™, for example.
