53 /* --- @xmalloc@ --- *
55 * Arguments: @size_t sz@ = size of block to allocate
57 * Returns: Pointer to allocated block.
59 * Use: Allocates memory. If there's not enough memory, the
60 * exception @EXC_NOMEM@ is thrown.
63 void *xmalloc(size_t sz)
71 /* --- @xstrdup@ --- *
73 * Arguments: @const char *s@ = pointer to a string
75 * Returns: Pointer to a copy of the string.
77 * Use: Copies a string (like @strdup@ would, if it existed). If
78 * there's not enough memory, the exception @EXC_NOMEM@ is
82 char *xstrdup(const char *s)
84 size_t sz = strlen(s) + 1;
85 char *p = xmalloc(sz);
90 /* --- @xrealloc@ --- *
92 * Arguments: @void *p@ = pointer to a block of memory
93 * @size_t sz@ = new size desired for the block
95 * Returns: Pointer to the resized memory block (which is almost
96 * certainly not in the same place any more).
98 * Use: Resizes a memory block. If there's not enough memory, the
99 * exception @EXC_NOMEM@ is thrown.
102 void *xrealloc(void *p, size_t sz)
