The * FUNC_ENTER() macro clears the error stack whenever an API * function is entered. When an error is detected, an entry is * pushed onto the stack. As the functions unwind additional * entries are pushed onto the stack. The API function will * return some indication that an error occurred and the * application can print the error stack. * * Certain API functions in the H5E package (such as H5Eprint()) * do not clear the error stack. Otherwise, any function which * doesn't have an underscore immediately after the package name * will clear the error stack. For instance, H5Fopen() clears * the error stack while H5F_open() does not. * * An error stack has a fixed maximum size. If this size is * exceeded then the stack will be truncated and only the * inner-most functions will have entries on the stack. This is * expected to be a rare condition. * * Each thread has its own error stack, but since * multi-threading has not been added to the library yet, this * package maintains a single error stack. The error stack is * statically allocated to reduce the complexity of handling * errors within the H5E package. * */ #include "H5private.h" /* Generic Functions */ #include "H5Iprivate.h" /* IDs */ #include "H5Eprivate.h" /* Private error routines */ #include "H5MMprivate.h" /* Memory management */ #define PABLO_MASK H5E_mask /* Interface initialization? */ static int interface_initialize_g = 0; #define INTERFACE_INIT H5E_init_interface /* HDF5 error class ID */ hid_t H5E_ERR_CLS_g = FAIL; /* * Predefined errors.

It contains all the * information about a particular error. * * CLIENT_DATA is the same pointer that was passed as the * CLIENT_DATA argument of H5Ewalk(). It is expected to be a * file pointer (or stderr if null). * * Return: Non-negative on success/Negative on failure * * Programmer: Robb Matzke * Friday, December 12, 1997 * * Modifications: * *------------------------------------------------------------------------- */ static herr_t H5E_walk_cb(unsigned n, const H5E_error_t *err_desc, void *client_data) { H5E_print_t *eprint = (H5E_print_t *)client_data; FILE *stream; /* I/O stream to print output to */ H5E_cls_t *cls_ptr; /* Pointer to error class */ H5E_msg_t *maj_ptr; /* Pointer to major error info */ H5E_msg_t *min_ptr; /* Pointer to minor error info */ const char *maj_str = "No major description"; /* Major error description */ const char *min_str = "No minor description"; /* Minor error description */ unsigned have_desc=1; /* Flag to indicate whether the error has a "real" description */ FUNC_ENTER_NOINIT(H5E_walk_cb) /* Check arguments */ assert (err_desc); /* If no client data was passed, output to stderr */ if (!client_data) stream = stderr; else stream = eprint->stream; /* Get descriptions for the major and minor error numbers */ maj_ptr = H5I_object_verify(err_desc->maj_id, H5I_ERROR_MSG); min_ptr = H5I_object_verify(err_desc->min_id, H5I_ERROR_MSG); assert(maj_ptr && min_ptr); if(maj_ptr->msg) maj_str = maj_ptr->msg; if(min_ptr->msg) min_str = min_ptr->msg; /* Get error class info */ cls_ptr = maj_ptr->cls; /* Print error class header if new class */ if(eprint->cls.lib_name==NULL || HDstrcmp(cls_ptr->lib_name, eprint->cls.lib_name)) { /* update to the new class information */ if(cls_ptr->cls_name) eprint->cls.cls_name = cls_ptr->cls_name; if(cls_ptr->lib_name) eprint->cls.lib_name = cls_ptr->lib_name; if(cls_ptr->lib_vers) eprint->cls.lib_vers = cls_ptr->lib_vers; fprintf (stream, "%s-DIAG: Error detected in %s (%s) ", cls_ptr->cls_name, cls_ptr->lib_name, cls_ptr->lib_vers); /* try show the process or thread id in multiple processes cases*/ #ifdef H5_HAVE_PARALLEL { int mpi_rank, mpi_initialized; MPI_Initialized(&mpi_initialized); if (mpi_initialized){ MPI_Comm_rank(MPI_COMM_WORLD,&mpi_rank); fprintf (stream, "MPI-process %d", mpi_rank); }else fprintf (stream, "thread 0"); } #elif defined(H5_HAVE_THREADSAFE) fprintf (stream, "thread %d", (int)pthread_self()); #else fprintf (stream, "thread 0"); #endif fprintf (stream, ":\n"); } /* Check for "real" error description - used to format output more nicely */ if(err_desc->desc==NULL || HDstrlen(err_desc->desc)==0) have_desc=0; /* Print error message */ fprintf (stream, "%*s#%03u: %s line %u in %s()%s%s\n", H5E_INDENT, "", n, err_desc->file_name, err_desc->line, err_desc->func_name, (have_desc ?
