 The functions in these groups perform the memory operations and character class related operations respectively. They follow the style of the memory allocation functions and character class handling functions of the standard C library except that they accept a pointer to the user-defined data as the first argument, thus providing more flexibility. The pointer to the user-defined data is specified into the ##custom_data## field of each group. The ##realloc## field, however, can be ##ASE_NULL##, in which case the functions pointed by the free and the malloc field replace the role of the function pointed by the ##realloc## field.
