This happens not only when you use link see Hard Links but also when you rename a file with rename see Renaming Files. Duplicate descriptors do count toward this limit. Note that any number of linked channels count as just one file opening; see Linked Channels. Often using a debugger to run a program is considered having it open for writing and will cause this error. Every library function that returns this error code also generates a SIGPIPE signal; this signal terminates the program if not handled or blocked.

To make your program portable, you should check for both codes and treat them the same. The values are always the same, on every operating system.
