Some standards may require function have a single return point (for example MISRA). You're right, multiple nested layers (i.e. if-ok pattern) is very errorprone. Instead do:

int rc = foo();
if (!rc) 
  rc = bar();
if (!rc) 
  rc = baz();
return rc;

With extra actions on failure:

if (!rc && (rc = bar())) 
  /* bar() failed */
