spt_puts(2) OSS System Calls Reference Manual
NAME
spt_puts - Initiates thread-aware puts( ) function.
LIBRARY
G-series native OSS processes: /G/system/sysnn/zsptsrl
H-series OSS processes: /G/system/zdllnnn/zsptdll
SYNOPSIS
#include <spthread.h>
int spt_puts(
const char *string);
PARAMETERS
See the puts(3) reference page either online or in the Open System Services Library Calls Refer-
ence Manual.
DESCRIPTION
This is a thread-aware version of the puts( ) function. The file descriptor underlying standard
output must be nonblocking for this function to be thread-aware.
The following macro maps spt_puts() to puts( ) and has been defined in spthread.h:
#define puts(string) spt_puts(string)
This macro is available only when SPT_THREAD_AWARE has been defined before including
spthread.h, similar to the following:
#define SPT_THREAD_AWARE
RETURN VALUES
See the puts(3) reference page. The following also applies:
• The value of errno is never set to [EAGAIN] or [EWOULDBLOCK].
• If the file descriptor underlying standard output becomes invalid (is closed by another
thread), EOF is returned with an errno of [EBADF].
• If a signal is received via the pthread_kill() function and is not blocked, ignored, or
handled, EOF is returned with an errno of [EINTR].
STANDARDS CONFORMANCE
This function is an extension to the XPG4 Version 2 specification. Interfaces documented on this
reference page conform to the following industry standards:
• IEEE Std 1003.1c-1995, POSIX System Application Program Interface
The use of the header file spthread.h is an HP exception to the POSIX standard.
