58 /* --- @xmalloc@ --- *
60 * Arguments: @size_t sz@ = size of block to allocate
62 * Returns: Pointer to allocated block.
64 * Use: Allocates memory. If there's not enough memory, the
65 * exception @EXC_NOMEM@ is thrown.
68 extern void *xmalloc(size_t /*sz*/);
70 /* --- @xstrdup@ --- *
72 * Arguments: @const char *s@ = pointer to a string
74 * Returns: Pointer to a copy of the string.
76 * Use: Copies a string (like @strdup@ would, if it existed). If
77 * there's not enough memory, the exception @EXC_NOMEM@ is
81 extern char *xstrdup(const char */*s*/);
83 /* --- @xrealloc@ --- *
85 * Arguments: @void *p@ = pointer to a block of memory
86 * @size_t sz@ = new size desired for the block
88 * Returns: Pointer to the resized memory block (which is almost
89 * certainly not in the same place any more).
91 * Use: Resizes a memory block. If there's not enough memory, the
92 * exception @EXC_NOMEM@ is thrown.
95 extern void *xrealloc(void */*p*/, size_t /*sz*/);
