Use of the malloc/free/realloc/calloc/valloc/memalign/posix_memalign

APIs is not allowed in the QEMU codebase. Instead of these routines,


  		





  80
  
  
    
use the replacement qemu_malloc/qemu_mallocz/qemu_realloc/qemu_free or


  		





  
  80
  
    
use the replacement g_malloc/g_malloc0/g_realloc/g_free or


  		





  81
  81
  
    
qemu_vmalloc/qemu_memalign/qemu_vfree APIs.

Please note that NULL check for the qemu_malloc result is redundant and


  		





  84
  
  
    
that qemu_malloc() call with zero size is not allowed.

that g_malloc() call with zero size is not allowed.

Memory allocated by qemu_vmalloc or qemu_memalign must be freed with


  		





  87

qemu_vfree, since breaking this will cause problems on Win32 and user

There are also replacement character processing macros for isxyz and toxyz,


  		





  109
  109
  
    
so instead of e.g. isalnum you should use qemu_isalnum.

Because of the memory management rules, you must use qemu_strdup/qemu_strndup

Because of the memory management rules, you must use g_strdup/g_strndup

instead of plain strdup/strndup.
