Helper functions for dealing with Globus Errno Error objects.

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

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

Parameters:

error The error object for which to perform the check
module The module descriptor to check for
system_errno The errno to check for

Returns:

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

Allocate and initialize an error of type GLOBUS_ERROR_TYPE_GLOBUS which contains a causal error of type GLOBUS_ERROR_TYPE_ERRNO.

Parameters:

base_source Pointer to the originating module.
system_errno The errno to use when generating the causal error.
type The error type. We may reserve part of this namespace for common errors. Errors not in this space are assumed to be local to the originating module.
source_file Name of file. Use FILE
source_func Name of function. Use _globus_func_name and declare your func with GlobusFuncName(<name>)
source_line Line number. Use LINE
short_desc_format Short format string giving a succinct description of the error. To be passed on to the user.
... Arguments for the format string.

Returns:

The resulting error object. It is the user's responsibility to eventually free this object using globus_object_free(). A globus_result_t may be obtained by calling globus_error_put() on this object.
