@deftypefn Replacement void* xmalloc (size_t)
Allocate memory without fail. If @code{malloc} fails, this will print
-a message to stderr (using the name set by @code{xmalloc_set_program_name},
+a message to @code{stderr} (using the name set by
+@code{xmalloc_set_program_name},
if any) and then call @code{xexit}. Note that it is therefore safe for
a program to contain @code{#define malloc xmalloc} in its source.
@end deftypefn
-@deftypefn Replacement void* xrealloc (void*, size_t)
+@deftypefn Replacement void* xrealloc (void *@var{ptr}, size_t @var{size})
Reallocate memory without fail. This routine functions like @code{realloc},
but will behave the same as @code{xmalloc} if memory cannot be found.
@end deftypefn
-@deftypefn Replacement void* xcalloc (size_t, size_t)
+@deftypefn Replacement void* xcalloc (size_t @var{nelem}, size_t @var{elsize})
Allocate memory without fail, and set it to zero. This routine functions
like @code{calloc}, but will behave the same as @code{xmalloc} if memory
