60 /* --- @xmalloc@ --- *
62 * Arguments: @size_t sz@ = size of block to allocate
64 * Returns: Pointer to allocated block.
66 * Use: Allocates memory. If there's not enough memory, the
67 * exception @EXC_NOMEM@ is thrown.
70 void *xmalloc(size_t sz
)
78 /* --- @xstrdup@ --- *
80 * Arguments: @const char *s@ = pointer to a string
82 * Returns: Pointer to a copy of the string.
84 * Use: Copies a string (like @strdup@ would, if it existed). If
85 * there's not enough memory, the exception @EXC_NOMEM@ is
89 char *xstrdup(const char *s
)

97 /* --- @xrealloc@ --- *
99 * Arguments: @void *p@ = pointer to a block of memory
100 * @size_t sz@ = new size desired for the block
102 * Returns: Pointer to the resized memory block (which is almost
103 * certainly not in the same place any more).
105 * Use: Resizes a memory block. If there's not enough memory, the
106 * exception @EXC_NOMEM@ is thrown.
