Under DSO context we need stubs inside the Apache core code ** to make sure the MM library's code is actually available ** to the module DSOs. ** ** 2. When the MM library cannot be built on the current platform ** still provide dummy stubs so modules using the ap_mm_xxx() ** functions can be still built. But modules should use ** ap_mm_useable() to find out whether they really can use ** the MM stuff. */ /* * "What you see is all you get." * -- Brian Kernighan */ #include "httpd.h" #include "ap_mm.h" #ifdef EAPI_MM #include "mm.h" API_EXPORT(int) ap_mm_useable(void) { return TRUE; } #define STUB(val,nul) { return val; } #define STUB_STMT(stmt) { stmt; return; } #else API_EXPORT(int) ap_mm_useable(void) { return FALSE; } #define STUB(val,nul) { return nul; } #define STUB_STMT(stmt) { return; } #endif API_EXPORT(int) ap_MM_create(size_t size, char *file) STUB(MM_create(size, file), FALSE) API_EXPORT(int) ap_MM_permission(mode_t mode, uid_t owner, gid_t group) STUB(MM_permission(mode, owner, group), -1) API_EXPORT(void) ap_MM_destroy(void) STUB_STMT(MM_destroy()) API_EXPORT(int) ap_MM_lock(ap_mm_lock_mode mode) STUB(MM_lock(mode), FALSE) API_EXPORT(int) ap_MM_unlock(void) STUB(MM_unlock(), FALSE) API_EXPORT(void *) ap_MM_malloc(size_t size) STUB(MM_malloc(size), NULL) API_EXPORT(void *) ap_MM_realloc(void *ptr, size_t size) STUB(MM_realloc(ptr, size), NULL) API_EXPORT(void) ap_MM_free(void *ptr) STUB_STMT(MM_free(ptr)) API_EXPORT(void *) ap_MM_calloc(size_t number, size_t size) STUB(MM_calloc(number, size), NULL) API_EXPORT(char *) ap_MM_strdup(const char *str) STUB(MM_strdup(str), NULL) API_EXPORT(size_t) ap_MM_sizeof(void *ptr) STUB(MM_sizeof(ptr), 0) API_EXPORT(size_t) ap_MM_maxsize(void) STUB(MM_maxsize(), 0) API_EXPORT(size_t) ap_MM_available(void) STUB(MM_available(), 0) API_EXPORT(char *) ap_MM_error(void) STUB(MM_error(), NULL) API_EXPORT(AP_MM *) ap_mm_create(size_t size, char *file) STUB(mm_create(size, file), NULL) API_EXPORT(int) ap_mm_permission(AP_MM *mm, mode_t mode, uid_t owner, gid_t group) STUB(mm_permission(mm, mode, owner, group), -1) API_EXPORT(void) ap_mm_destroy(AP_MM *mm) STUB_STMT(mm_destroy(mm)) API_EXPORT(int) ap_mm_lock(AP_MM *mm, ap_mm_lock_mode mode) STUB(mm_lock(mm, mode), FALSE) API_EXPORT(int) ap_mm_unlock(AP_MM *mm) STUB(mm_unlock(mm), FALSE) API_EXPORT(void *) ap_mm_malloc(AP_MM *mm, size_t size) STUB(mm_malloc(mm, size), NULL) API_EXPORT(void *) ap_mm_realloc(AP_MM *mm, void *ptr, size_t size) STUB(mm_realloc(mm, ptr, size), NULL) API_EXPORT(void) ap_mm_free(AP_MM *mm, void *ptr) STUB_STMT(mm_free(mm, ptr)) API_EXPORT(void *) ap_mm_calloc(AP_MM *mm, size_t number, size_t size) STUB(mm_calloc(mm, number, size), NULL) API_EXPORT(char *) ap_mm_strdup(AP_MM *mm, const char *str) STUB(mm_strdup(mm, str), NULL) API_EXPORT(size_t) ap_mm_sizeof(AP_MM *mm, void *ptr) STUB(mm_sizeof(mm, ptr), 0) API_EXPORT(size_t) ap_mm_maxsize(void) STUB(mm_maxsize(), 0) API_EXPORT(size_t) ap_mm_available(AP_MM *mm) STUB(mm_available(mm), 0) API_EXPORT(char *) ap_mm_error(void) STUB(mm_error(), NULL) API_EXPORT(void) ap_mm_display_info(AP_MM *mm) STUB_STMT(mm_display_info(mm)) API_EXPORT(void *) ap_mm_core_create(size_t size, char *file) STUB(mm_core_create(size, file), NULL) API_EXPORT(int) ap_mm_core_permission(void *core, mode_t mode, uid_t owner, gid_t group) STUB(mm_core_permission(core, mode, owner, group), -1) API_EXPORT(void) ap_mm_core_delete(void *core) STUB_STMT(mm_core_delete(core)) API_EXPORT(size_t) ap_mm_core_size(void *core) STUB(mm_core_size(core), 0) API_EXPORT(int) ap_mm_core_lock(void *core, ap_mm_lock_mode mode) STUB(mm_core_lock(core, mode), FALSE) API_EXPORT(int) ap_mm_core_unlock(void *core) STUB(mm_core_unlock(core), FALSE) API_EXPORT(size_t) ap_mm_core_maxsegsize(void) STUB(mm_core_maxsegsize(), 0) API_EXPORT(size_t) ap_mm_core_align2page(size_t size) STUB(mm_core_align2page(size), 0) API_EXPORT(size_t) ap_mm_core_align2word(size_t size) STUB(mm_core_align2word(size), 0) API_EXPORT(void) ap_mm_lib_error_set(unsigned int type, const char *str) STUB_STMT(mm_lib_error_set(type, str)) API_EXPORT(char *) ap_mm_lib_error_get(void) STUB(mm_lib_error_get(), NULL) API_EXPORT(int) ap_mm_lib_version(void) STUB(mm_lib_version(), 0)
