56 /* --- @xmalloc@ --- *
58 * Arguments: @size_t sz@ = size of block to allocate
60 * Returns: Pointer to allocated block.
62 * Use: Allocates memory. If there's not enough memory, the
63 * exception @EXC_NOMEM@ is thrown.
66 void *xmalloc(size_t sz)
74 /* --- @xstrdup@ --- *
76 * Arguments: @const char *s@ = pointer to a string
78 * Returns: Pointer to a copy of the string.
80 * Use: Copies a string (like @strdup@ would, if it existed). If
81 * there's not enough memory, the exception @EXC_NOMEM@ is
85 char *xstrdup(const char *s)
87 size_t sz = strlen(s) + 1;
88 char *p = xmalloc(sz);
93 /* --- @xrealloc@ --- *
95 * Arguments: @void *p@ = pointer to a block of memory
96 * @size_t sz@ = new size desired for the block
98 * Returns: Pointer to the resized memory block (which is almost
99 * certainly not in the same place any more).
101 * Use: Resizes a memory block. If there's not enough memory, the
102 * exception @EXC_NOMEM@ is thrown.
105 void *xrealloc(void *p, size_t sz)
