rset.h File

Purpose

Contains enums and definitions to manipulate process' partition rsets.

Syntax

#include <pwd.h>

Description

The rset.h header contains enums and definitions to manipulate process' partition resource sets.

char       *pw_name      user's login name 
uid_t       pw_uid       numerical user ID
gid_t       pw_gid       numerical group ID
char       *pw_dir       initial working directory
char       *pw_shell     program to use as shell

The gid_t and uid_t types are defined as described in sys/types.h.

The following are declared as functions and may also be defined as macros. Function prototypes must be provided for use with an ISO C compiler.

struct   passwd    *getpwuid(uid_t);
int                 getpwnam_r(const char *, struct passwd *, char *, size_t, struct passwd **);
int                 getpwuid_r(uid_t, struct passwd *, char *, size_t, struct passwd **);
void                endpwent(void);
struct   passwd    *getpwent(void);
void                setpwent(void);

The following resource set APIs are exported by the kernel to kernel extensions. They will continue to be exported with semantics similar to the corresponding user space APIs.

• krs_numrads
• krs_getrad
• krs_getinfo
• krs_alloc
• krs_free
• krs_op
• kra_creatp

The following new kernel exported kernel extension APIs will be provided. Their APIs will be similar to the corresponding user space APIs.

• krs_init
• kra_attachrset
• kra_detachrset
• kra_getrset

There are currently no exported kernel extension services for getting or setting a process's partition rset. The following new kernel extension APIs will be provided to manipulate process's partition rsets:

• krs_getpartition
• krs_setpartition

There are currently no exported kernel extension services to access the rset registry. Kernel extension APIs will not be provided.
