48 /* --- @xmalloc@ --- *
50 * Arguments: @size_t sz@ = size of block to allocate
52 * Returns: Pointer to allocated block.
54 * Use: Allocates memory. If there's not enough memory, the
55 * exception @EXC_NOMEM@ is thrown.
58 extern void *xmalloc(size_t /*sz*/);
60 /* --- @xstrdup@ --- *
62 * Arguments: @const char *s@ = pointer to a string
64 * Returns: Pointer to a copy of the string.
66 * Use: Copies a string (like @strdup@ would, if it existed). If
67 * there's not enough memory, the exception @EXC_NOMEM@ is
71 extern char *xstrdup(const char */*s*/);
73 /* --- @xrealloc@ --- *
75 * Arguments: @void *p@ = pointer to a block of memory
76 * @size_t sz@ = new size desired for the block
78 * Returns: Pointer to the resized memory block (which is almost
79 * certainly not in the same place any more).
81 * Use: Resizes a memory block. If there's not enough memory, the
82 * exception @EXC_NOMEM@ is thrown.
85 extern void *xrealloc(void */*p*/, size_t /*sz*/);
