put_regTimerHandler(2) OSS System Calls Reference Manual
NAME
put_regTimerHandler - Registers a user-supplied timer callback function
LIBRARY
32-bit H-series and J-series OSS processes: /G/system/zdllnnn/zputdll
64-bit H-series and J-series OSS processes: /G/system/zdllnnn/yputdll
SYNOPSIS
#include <pthread.h>
put_error_t put_regTimerHandler(
const put_TimerHandler_p functionPtr);
PARAMETERS
functionPtr Specifies the user-supplied callback function; this function must not block I/O.
DESCRIPTION
This function registers a user-supplied timer callback function.
To use this function on systems running H06.21 or later RVUs or J06.10 or later RVUs, you must
perform all of the following 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
this function with 32-bit or 64-bit applications.
To use this function in a 32-bit application on systems running H06.24 or later RVUs or J06.13 or
later RVUs, perform the same tasks (described above) used to enable the function on systems
running H06.21/J06.10 or later RVUs.
To use this function in a 64-bit application on systems running H06.24 or later RVUs or J06.13 or
later RVUs, you must perform all of the following 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.
• Compile the application using the -Wlp64 compiler command option.
• Link the application to the yputdll library (/G/system/zdllnnn/yputdll).
RETURN VALUES
PUT_SUCCESS
The callback function was successfully registered.
PUT_ERROR functionPtr is NULL.
PUT_ERROR The specified callback function is already registered.
