Caveat utilitor! * * In addition, there were other symbols defined in a header of this name by * earlier releases of COHERENT that have some historical basis of use by * applications, such as NBPC. Such symbols have not been carried over as * not only do portable equivalents exist but these symbols do not match the * required contents as defined by the ABI or iBCS2 specifications. * * Therefore, we define below only a minimal set of symbols and then only if * explicitly required by the _BCS_PARAM_H feature-test. The mere fact that * this header exists will allow most portable software to compile cleanly in * the few cases where this header is included (such as in certain GNU * software that includes this header on the basis that the definitions might * be needed as a fallback if more portable alternatives fail). */ #include <limits.h> #if _BCS_PARAM_H || _ABI_PARAM_H || _DDI_DKI #define NBPSCTR 512 #if _BCS_PARAM_H || _ABI_PARAM_H #define CANBSIZ 256 #define HZ 100 #define TICK 10000000 #define NBBY 8 #if _BCS_PARAM_H #define DEV_BSIZE NBPSCTR #define MAXPID PID_MAX #define MAXUID UID_MAX #define MAXLINK LINK_MAX #define NCARGS ARG_MAX #define NOFILES_MIN 20 #define NOFILES_MAX 100 /* * Some software looks for NGROUPS in this file, and never looks for the * correct symbol in <limits.h>.
