Detailed Description

Helper functions for dealing with Globus Generic Error objects.

This section defines utility functions for dealing with Globus Generic Error objects.

Function Documentation

globus_bool_t globus_error_match (globus_object_t * error, globus_module_descriptor_t * module, int type)

Check whether the error originated from a specific module and is of a specific type.

This function checks whether the error or any of it's causative errors originated from a specific module and is of a specific type. If the module descriptor is left unspecified this function will check for any error of the specified type and vice versa.

Parameters:

error The error object for which to perform the check
module The module descriptor to check for
type The type to check for

Returns:

GLOBUS_TRUE - the error matched the module and type GLOBUS_FALSE - the error failed to match the module and type

char* globus_error_print_chain (globus_object_t * error)

Return a string containing all printable errors found in a error object and it's causative error chain.

If the GLOBUS_ERROR_VERBOSE env is set, file, line and function info will also be printed (where available). Otherwise, only the module name will be printed.

Parameters:

error The error to print

Returns:

A string containing all printable errors. This string needs to be freed by the user of this function.

References globus_error_get_cause().

char* globus_error_print_friendly (globus_object_t * error)

Return a string containing error messages from the top 1 and bottom 3 objects, and, if found, show a friendly error message.

The error chain will be searched from top to bottom until a friendly handler is found and a friendly message is created.

If the GLOBUS_ERROR_VERBOSE env is set, then the result from globus_error_print_chain() will be used.

Parameters:

error The error to print

Returns:

A string containing a friendly error message. This string needs to be freed by the user of this function.
