Unfortunately, no similar 38 * workaround exists for lint's pass2, which requires definitions for all 39 * symbols in order to properly perform cross-checks. 40 * 41 * Thus, this header file was created to address the problems: 42 * 43 * - The "extern" problem. All files beneath stand/lib should #include 44 * this file rather than "extern" the symbol. Additionally, existing 45 * externs should be removed as convenient. 46 * 47 * Of course, eventually some brave soul needs to venture over to the 48 * slums of psm/stand and add all the proper header files, at which 49 * point this file can be disposed of. 50 * 51 * Note that the set of symbols shared between stand/lib and psm/stand is 52 * itself a moving target. As such, this file should be updated as needed 53 * so that it always contains the *minimum* set of shared symbols needed to 54 * avoid externs and placate lint. 55 */ 56 57 #include <sys/saio.h> 58 59 #ifdef __cplusplus 60 extern "C" { 61 #endif 62 63 /* 64 * From psm/stand/boot/$(MACH)/common/fsconf.c: 65 */ 66 extern int nfs_readsize; 67 extern int boot_nfsw; 68 extern struct boot_fs_ops *boot_fsw[]; 69 extern struct boot_fs_ops *extendfs_ops; 70 extern struct boot_fs_ops *origfs_ops; 71 72 /* 73 * From psm/stand/boot/common/boot.c: 74 */ 75 extern int boothowto; 76 extern int verbosemode; 77 extern char *systype; 78 extern struct memlist *pfreelistp; 79 extern struct memlist *vfreelistp; 80 extern void set_default_filename(char *); 81 82 /* 83 * From psm/stand/boot/common/heap_kmem.c: 84 */ 85 extern void *bkmem_alloc(size_t); 86 extern void *bkmem_zalloc(size_t); 87 extern void bkmem_free(void *, size_t); 88 89 /* 90 * From psm/stand/boot/$(MACH)/common/$(MACH)_standalloc.c: 91 */ 92 extern caddr_t resalloc(enum RESOURCES, size_t, caddr_t, int); 93 extern void resfree(enum RESOURCES, caddr_t, size_t); 94 extern void reset_alloc(void); 95 96 /* 97 * From psm/stand/lib/names/$(MACH)/common/mfgname.c: (libnames) 98 */ 99 extern char *get_mfg_name(void); 100 101 /* 102 * From psm/stand/boot/i386/common/boot_plat.c or 103 * psm/stand/boot/sparcv9/sun4u/machdep.c: 104 */ 105 extern int pagesize; 106 extern int global_pages; 107 108 #ifdef __sparc 109 /* 110 * From psm/stand/boot/sparc/common/fsconf.c: 111 */ 112 extern char *bootp_response; 113 #endif /* __sparc */ 114 115 #ifdef __cplusplus 116 } 117 #endif 118 119 #endif /* _SYS_BOOTSYMS_H */ 120
