hwlocalit...ct_strings(3) Library Functions Manual hwlocalit...ct_strings(3) NAME hwlocality_object_strings - Converting between Object Types and Attributes, and Strings SYNOPSIS Functions const char * hwloc_obj_type_string (hwloc_obj_type_t type) int hwloc_obj_type_snprintf (char *restrict string, size_t size, hwloc_obj_t obj, int verbose) int hwloc_obj_attr_snprintf (char *restrict string, size_t size, hwloc_obj_t obj, const char *restrict separator, int verbose) int hwloc_type_sscanf (const char *string, hwloc_obj_type_t *typep, union hwloc_obj_attr_u *attrp, size_t attrsize) int hwloc_type_sscanf_as_depth (const char *string, hwloc_obj_type_t *typep, hwloc_topology_t topology, int *depthp) Detailed Description Function Documentation int hwloc_obj_attr_snprintf (char *restrict string, size_t size, hwloc_obj_t obj, const char *restrict separator, int verbose) Stringify the attributes of a given topology object into a human- readable form. Attribute values are separated by separator. Only the major attributes are printed in non-verbose mode. If size is 0, string may safely be NULL. Returns the number of characters that were actually written if not truncating, or that would have been written (not including the ending \0). int hwloc_obj_type_snprintf (char *restrict string, size_t size, hwloc_obj_t obj, int verbose) Stringify the type of a given topology object into a human-readable form. Contrary to hwloc_obj_type_string(), this function includes object-specific attributes (such as the Group depth, the Bridge type, or OS device type) in the output, and it requires the caller to provide the output buffer. The output is guaranteed to be the same for all objects of a same topology level. If verbose is 1, longer type names are used, e.g. L1Cache instead of L1. The output string may be parsed back by hwloc_type_sscanf(). If size is 0, string may safely be NULL. Returns the number of characters that were actually written if not truncating, or that would have been written (not including the ending \0). const char * hwloc_obj_type_string (hwloc_obj_type_t type) Return a constant stringified object type. This function is the basic way to convert a generic type into a string. The output string may be parsed back by hwloc_type_sscanf(). hwloc_obj_type_snprintf() may return a more precise output for a specific object, but it requires the caller to provide the output buffer. Returns A constant string containing the object type name or 'Unknown'. int hwloc_type_sscanf (const char * string, hwloc_obj_type_t * typep, union hwloc_obj_attr_u * attrp, size_t attrsize) Return an object type and attributes from a type string. Convert strings such as 'Package' or 'L1iCache' into the corresponding types. Matching is case-insensitive, and only the first letters are actually required to match. The matched object type is set in typep (which cannot be NULL). Type-specific attributes, for instance Cache type, Cache depth, Group depth, Bridge type or OS Device type may be returned in attrp. Attributes that are not specified in the string (for instance 'Group' without a depth, or 'L2Cache' without a cache type) are set to -1. attrp is only filled if not NULL and if its size specified in attrsize is large enough. It should be at least as large as union hwloc_obj_attr_u. Returns 0 if a type was correctly identified, otherwise -1. Note This function is guaranteed to match any string returned by hwloc_obj_type_string() or hwloc_obj_type_snprintf(). This is an extended version of the now deprecated hwloc_obj_type_sscanf(). int hwloc_type_sscanf_as_depth (const char * string, hwloc_obj_type_t * typep, hwloc_topology_t topology, int * depthp) Return an object type and its level depth from a type string. Convert strings such as 'Package' or 'L1iCache' into the corresponding types and return in depthp the depth of the corresponding level in the topology topology. If no object of this type is present on the underlying architecture, HWLOC_TYPE_DEPTH_UNKNOWN is returned. If multiple such levels exist (for instance if giving Group without any depth), the function may return HWLOC_TYPE_DEPTH_MULTIPLE instead. The matched object type is set in typep if typep is non NULL. Note This function is similar to hwloc_type_sscanf() followed by hwloc_get_type_depth() but it also automatically disambiguates multiple group levels etc. This function is guaranteed to match any string returned by hwloc_obj_type_string() or hwloc_obj_type_snprintf().
