printf(3) Guardian Native C Library Calls Reference Manual
ERRORS
The printf( ) function fails if the standard output stream is unbuffered, or if the buffer needed to
be flushed and the function call caused an underlying write() or lseek() function to be invoked.
In addition, if the printf( ) function fails, errno is set to one of the following values:
[EAGAIN] The O_NONBLOCK flag is set for the file descriptor underlying the output
stream and the process would be delayed in the write operation.
[EBADF] The file descriptor underlying the output stream is not a valid file descriptor open
for writing.
[EFBIG] An attempt was made to write to a file that exceeds the process’s file size limit or
the maximum file size.
[EILSEQ] An invalid wide character was detected.
[EINTR] The operation was interrupted by a signal that was caught, and no data was
transferred.
[EINVAL] There are insufficient arguments.
[EIO] The implementation supports job control; the process is a member of a back-
ground process group attempting to write to its controlling terminal; TOSTOP is
set; the process is neither ignoring nor blocking SIGTTOU; and the process
group of the process is orphaned. This error might also be returned under
implementation-defined conditions.
[ENOMEM] Insufficient storage space was available.
[ENOSPC] There was no free space remaining on the device containing the file.
[ENXIO] A request was made of a nonexistent device, or the request was outside the capa-
bilities of the device.
[EPIPE] An attempt was made to write to a pipe or FIFO that is not open for reading by
any process. A SIGPIPE signal will also be sent to the process.

Functions: fp_class(3), fprintf(3), isnan(3), toascii(3), putc(3), scanf(3), sprintf(3).
STANDARDS CONFORMANCE
The following are HP extensions to the XPG4 Version 2 specification:
• The conversion specifier L followed by a d, i, n, o,orx indicates that the argument will
be treated as a long long, which is a 64-bit integer data type.
• The conversion specifier ll followed by a d, i, n, o,orx indicates that the argument will
be treated as an unsigned long long, which is a 64-bit integer data type.
