Function Documentation

◆ __get_cpu_model()

__Z_EXPORT char * __get_cpu_model	(	char *	buffer,
		size_t	size
	)

Gets the 4 character CPU model of the system, including the null terminating character. Truncated if buffer size is too small.

Parameters

buffer	pointer to the buffer where the cpu model is to be stored
size	the size of the buffer

Returns: pointer to the buffer.

◆ __get_num_frames()

__Z_EXPORT int __get_num_frames ( void )

Get the number of frames currently available to the system

Returns: returns the number of available frames

◆ __get_num_online_cpus()

__Z_EXPORT int __get_num_online_cpus ( void )

Get the number of online CPUs

Returns: returns the number of online CPUs

◆ __get_os_level()

__Z_EXPORT oslvl_t __get_os_level ( void )

Get the OS level

Returns: the OS level as ZOSLVL_V2R1/2/3/4/5 (values are in ascending order)

◆ __is_os_level_at_or_above()

__Z_EXPORT bool __is_os_level_at_or_above ( oslvl_t level )

Check if current OS is at or above a given level

Returns: true if the current OS level is at or above the given level, and false otherwise

◆ __is_stfle_available()

__Z_EXPORT bool __is_stfle_available ( )

Check if STFLE (STORE FACILITY LIST EXTENDED) instruction is available

Returns: true if the STFLE instruction is available

◆ __is_vef1_available()

__Z_EXPORT bool __is_vef1_available ( )

Check if the current z arch includes Vector Enhancements Facility 1

Returns: true if Vector Enhancements Facility 1 instructions are available, and false otherwise

◆ __is_vxf_available()

__Z_EXPORT bool __is_vxf_available ( )

Check if the current z arch includes Vector Extension Facility

Returns: true if Vector Extension Facility instructions are available, and false otherwise
