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