osapi_machine_cpu_feature_S::avail
t_cpu_feature_size avail
Number of available CPU features (to speedup library functions)
Definition: machine_type_features.h:45
osapi_machine_cpu_feature_S
Define a type for CPU features.
Definition: machine_type_features.h:42
osapi_machine_cpu_feature_S::feature
_Bool feature[osapi_machine_cpu_feature_max+1]
