libc
Use the -l c option to qcc to link against this library. This library is usually included automatically.
The valloc() function allocates a heap block that's aligned on a page boundary. It's equivalent to:
memalign( sysconf( _SC_PAGESIZE ), size );
A pointer to the allocated block, or NULL if an error occurred (errno is set).
