23 | NAME | |
24 | xmalloc() - get memory or bust | |
25 | INDEX | |
26 | xmalloc() uses malloc() | |
27 | ||
28 | SYNOPSIS | |
29 | char * my_memory; | |
30 | ||
31 | my_memory = xmalloc(42); / * my_memory gets address of 42 chars * / | |
32 | ||
33 | DESCRIPTION | |
34 | ||
35 | Use xmalloc() as an "error-free" malloc(). It does almost the same job. | |
36 | When it cannot honour your request for memory it BOMBS your program | |
37 | with a "virtual memory exceeded" message. Malloc() returns NULL and | |
38 | does not bomb your program. | |
