Large Files and Applications

An existing application running on Solaris 2.x software should be checked for the following points:

• To make the application large-file compatible (for example, "large-file safe in Solaris 2.6"), examine the application's source code to ensure that use of existing interfaces is appropriate and ensure the correct error-handling characteristics when a large file is encountered.

• For your application to work with large files (for example, "large-file aware"), you must examine and modify your source code. Examples of areas to modify include:

  • Output and in-memory formatting strings such as %ld to %lld

  • Any variable used for temporary storage of sizes or offset information must be correctly sized to avoid truncation.

  • Function parameters and return values should be checked and corrected if necessary.
