explain_dup2_or_die(3) Library Functions Manual explain_dup2_or_die(3) NAME explain_dup2_or_die - duplicate a file descriptor and report errors SYNOPSIS #include <libexplain/dup2.h> void explain_dup2_or_die(int oldfd, int newfd); DESCRIPTION The explain_dup2_or_die function is used to call the dup2(2) system call. On failure an explanation will be printed to stderr, obtained from explain_dup2(3), and then the process terminates by calling exit(EXIT_FAILURE). This function is intended to be used in a fashion similar to the fol- lowing example: explain_dup2_or_die(oldfd, newfd); oldfd The oldfd, exactly as to be passed to the dup2(2) system call. newfd The newfd, exactly as to be passed to the dup2(2) system call. Returns: This function only returns on success. On failure, prints an explanation and exits.
