pthread_signal_to_cancel_np(2) OSS System Calls Reference Manual
NAME
pthread_signal_to_cancel_np - Cancels a thread if a specified signal is received
LIBRARY
G-series native OSS processes: /G/system/sysnn/zsptsrl
32-bit H-series and J-series OSS processes that use the POSIX User Thread Model library:
/G/system/zdllnnn/zputdll
64-bit H-series and J-series OSS processes that use the POSIX User Thread Model library:
/G/system/zdllnnn/yputdll
H-series and J-series OSS processes that use the Standard POSIX Threads library:
/G/system/zdllnnn/zsptdll
SYNOPSIS
#include <pthread.h> | #include <spthread.h>
/* pthread.h is required to use POSIX User Thread Model library */
/* spthread.h is required to use Standard POSIX Threads library */
int pthread_signal_to_cancel_np(
sigset_t *sigset,
pthread_t *thread);
PARAMETERS
sigset Specifies a signal mask containing a list of signals that, when received by the
thread, cancel the specified thread.
thread Specifies the thread to be canceled if a specified signal is received by the thread.
DESCRIPTION
The pthread_signal_to_cancel_np() function requests that the thread specified by the thread
parameter be canceled if one of the signals in the signal mask specified by the sigset parameter is
received by the process. The set of signals that can be specified is the same as the set for the
sigwait() function.
The sigset parameter is not validated. If it is invalid, this function returns successfully but nei-
ther the specified thread nor any previously specified thread is canceled if a signal occurs.
On systems running H06.21 or later H-series RVUs or J06.10 or later J-series RVUs, you can use
either the POSIX User Thread Model library or the Standard POSIX Threads library for threaded
applications.
To use this function in a threaded application that uses the POSIX User Thread Model library on
systems running H06.21 or later RVUs or J06.10 or later RVUs, you must perform all of the fol-
lowing tasks:
• Include the pthread.h header file in the application.
• Compile the application using the _PUT_MODEL_ feature test macro or equivalent
compiler command option.
• Link the application to the zputdll library (/G/system/zdllnnn/zputdll).
On systems running H06.24 or later H-series RVUs or J06.13 or later J-series RVUs, you can use
the POSIX User Thread Model library with 32-bit or 64-bit threaded applications.
To use this function in a 32-bit threaded application that uses the POSIX User Thread Model
library on systems running H06.24 or later RVUs or J06.13 or later RVUs, perform the same
tasks (described above) used to enable the POSIX User Thread Model library on systems running
H06.21/J06.10 or later RVUs.
