NAME explain_read_or_die - read from a file descriptor and report errors SYNOPSIS #include <libexplain/read.h> long explain_read_or_die(int fildes, const void *data, long data_size); DESCRIPTION The explain_read_or_die function is used to call the read(2) system call. On failure an explanation will be printed to stderr, obtained from explain_read(3), and then the process terminates by calling exit(EXIT_FAILURE). This function is intended to be used in a fashion similar to the following example: explain_read_or_die(fildes, data, data_size); fildes The fildes, exactly as to be passed to the read(2) system call. data The data, exactly as to be passed to the read(2) system call. data_size The data_size, exactly as to be passed to the read(2) system call. Returns: This function only returns on success. On failure, prints an explanation and exits.
