Variables | |
| int | merror_code |
| External variable to hold error code of the m17n library. | |
| void(*) | m17n_memory_full_handler (enum MErrorCode err) |
| Memory allocation error handler. | |
The first type is argument errors. When a library function is called with invalid arguments, it returns a value that indicates error and at the same time sets the external variable merror_code to a non-zero integer.
The second type is memory allocation errors. When the required amount of memory is not available on the system, m17n library functions call a function pointed to by the external variable m17n_memory_full_handler. The default value of the variable is a pointer to the default_error_handle() function, which just calls exit().
| enum MErrorCode |
Enumeration for error code of the m17n library.
When a library function is called with an invalid argument, it sets the external variable merror_code to one of these values. All the error codes are positive integers.
When a memory allocation error happens, the function pointed to by the external variable m17n_memory_full_handler is called with one of these values as an argument.
| int merror_code |
The external variable merror_code holds an error code of the m17n library. When a library function is called with an invalid argument, it sets this variable to one of enum MErrorCode.
This variable initially has the value 0.
| void(*) m17n_memory_full_handler(enum MErrorCode err) |
The external variable m17n_memory_full_handler holds a pointer to the function to call when a library function failed to allocate memory. err is one of enum MErrorCode indicating in which function the error occurred.
This variable initially points a function that simply calls the exit () function with err as an argument.
An application program that needs a different error handling can change this variable to point a proper function.
