#define PLATFORM_MAP_ANONYMOUS MAP_ANONYMOUS

This file is part of the CernVM File System.

Ensures that cvmfs aborts on out-of-memory errors.

Definition at line 22 of file smalloc.h.

Function Documentation

static void* __attribute__ ( (used) )

inlinestatic

Used when the caller remembers the size, so that it can call sxunmap later.

Free memory acquired by sxmmap.

Pointer is aligned at a multiple of the size. The size has to be a multiple of 2MB.

Definition at line 41 of file smalloc.h.

Here is the call graph for this function:

assert ( (mem||(size==0))&&"Out Of Memory" )

assert ( (mem||((count *size)==0))&&"Out Of Memory" )

assert ( (retval==0)&&"Invalid umnmap" )

static uint64_t RoundUp8 ( const uint64_t size )

inlinestatic

Round up size to the next larger multiple of 8. This is used to enforce 8-byte alignment.
