A nice idiom for malloc is to use the sizeof of the target of the pointer to which you are assigning its result (no explicit cast needed when assigning from a void * afaik, at least no warnings/errors here with gcc (Debian 4.4.5-8) 4.4.5):
$ gcc -std=c99 -Wall -pedantic -Wextra -Wno-unused-parameter
-o malloc malloc.c
#include <stdlib.h> struct foo { int bar, baz; double quux; }; int main(int argc, char **argv) { struct foo *f = malloc(sizeof(*f)); free(f); return 0; }
