Name
error -- Functions for allocating and manipulating lu_error structures.
Description
error.h includes declarations for allocating and
manipulating lu_error structures. These structures hold error and status
information passed between libuser, its modules, and applications.
Details
LU_ERROR_CHECK()
#define LU_ERROR_CHECK(err_p_p) |
Checks that the given pointer to a pointer to a struct does not already point
to a valid lu_error structure. This macro is used by many internal functions
to check that an error has not already occurred when they are invoked.
err_p_p : | A pointer to a struct lu_error * which will be checked. If there
|
lu_error_new ()
void lu_error_new (lu_error_t **error,
lu_status_t code,
const char *fmt,
...); |
lu_error_free ()
void lu_error_free (lu_error_t **error); |
Frees an lu_error structure.
error : | A pointer to a pointer to the structure to be freed. The pointer is set
to NULL after the error is freed.
|
lu_error_is_success ()
gboolean lu_error_is_success (lu_status_t status); |
Check if the error code held by an error structure is a success code.
lu_error_is_warning ()
gboolean lu_error_is_warning (lu_status_t status); |
Check if the error code held by an error structure is a warning code.
lu_error_is_error ()
gboolean lu_error_is_error (lu_status_t status); |
Check if the error code held by an error structure is an error code.
lu_strerror ()
const char* lu_strerror (lu_error_t *error); |
