LIBRARY
G-series native OSS processes: /G/system/sysnn/zsptsrl
H-series OSS processes: /G/system/zdllnnn/zsptdll
SYNOPSIS
#include <spthread.h>
int spt_close(

See the close(2) reference page.
DESCRIPTION
This is a thread-aware version of the close() function. Use spt_close() instead of close() to
ensure proper operation of the various thread-aware IO functions.
The following macro maps spt_close() to close() and has been defined in spthread.h:
#define close(filedes) spt_close(filedes)
This macro is available only when SPT_THREAD_AWARE has been defined before including
spthread.h, as follows:
#define SPT_THREAD_AWARE
RETURN VALUES
See the close(2) reference page.
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.
