// same time by one process.
#define SB_FILE_MAX_OPEN 256

// The current platform's file path component separator character. This is the
// character that appears after a directory in a file path. For example, the
// absolute canonical path of the file "/path/to/a/file.txt" uses '/' as a path
// component separator character.
#define SB_FILE_SEP_CHAR '/'

// The current platform's alternate file path component separator character.
// This is like SB_FILE_SEP_CHAR, except if your platform supports an alternate
// character, then you can place that here. For example, on windows machines,
// the primary separator character is probably '\', but the alternate is '/'.
#define SB_FILE_ALT_SEP_CHAR '/'

// The current platform's search path component separator character. When
// specifying an ordered list of absolute paths of directories to search for a

// --- Memory Configuration --------------------------------------------------

// be the hardware-defined physical page size, but it should be a multiple of
// it.
#define SB_MEMORY_PAGE_SIZE 4096

// Whether this platform has and should use an MMAP function to map physical
// memory to the virtual address space.
#define SB_HAS_MMAP 1

// Whether this platform can map executable memory. Implies SB_HAS_MMAP. This is
// required for platforms that want to JIT.
#define SB_CAN_MAP_EXECUTABLE_MEMORY 1

// Whether this platform has and should use an growable heap (e.g. with sbrk())
// to map physical memory to the virtual address space.
#define SB_HAS_VIRTUAL_REGIONS 0

// Specifies the alignment for IO Buffers, in bytes. Some low-level network APIs
// may require buffers to have a specific alignment, and this is the place to
// specify that.
#define SB_NETWORK_IO_BUFFER_ALIGNMENT 16

// Determines the alignment that allocations should have on this platform.

// Defines the path where memory debugging logs should be written to.

// --- Graphics Configuration ------------------------------------------------

// Specifies whether this platform supports a performant accelerated blitter
// API. The basic requirement is a scaled, clipped, alpha-blended blit.
#define SB_HAS_BLITTER 0

// Specifies the preferred byte order of color channels in a pixel. Refer to
// starboard/configuration.h for the possible values. EGL/GLES platforms should
// generally prefer a byte order of RGBA, regardless of endianness.

// Indicates whether or not the given platform supports bilinear filtering.
// This can be checked to enable/disable renderer tests that verify that this is
// working properly.
#define SB_HAS_BILINEAR_FILTERING_SUPPORT 1

// Indicates whether or not the given platform supports rendering of NV12
// textures. These textures typically originate from video decoders.
#define SB_HAS_NV12_TEXTURE_SUPPORT 0

// Whether the current platform should frequently flip their display buffer.
// If this is not required (e.g. SB_MUST_FREQUENTLY_FLIP_DISPLAY_BUFFER is set
// to 0), then optimizations where the display buffer is not flipped if the
// scene hasn't changed are enabled.

// On default Linux desktop, you must be a superuser in order to set real time
// scheduling on threads.
#define SB_HAS_THREAD_PRIORITY_SUPPORT 0

// Defines the maximum number of simultaneous threads for this platform. Some
// platforms require sharing thread handles with other kinds of system handles,

#define SB_MAX_THREADS 90

// The maximum number of thread local storage keys supported by this platform.
#define SB_MAX_THREAD_LOCAL_KEYS 512

#define SB_MAX_THREAD_NAME_LENGTH 16

// --- Tuneable Parameters ---------------------------------------------------

// Specifies the network receive buffer size in bytes, set via
// SbSocketSetReceiveBufferSize().
//
// Setting this to 0 indicates that SbSocketSetReceiveBufferSize() should
// not be called. Use this for OSs (such as Linux) where receive buffer
// auto-tuning is better.
//
// On some platforms, this may affect max TCP window size which may
// dramatically affect throughput in the presence of latency.
//
// If your platform does not have a good TCP auto-tuning mechanism,
// a setting of (128 * 1024) here is recommended.
#define SB_NETWORK_RECEIVE_BUFFER_SIZE (0)

// --- User Configuration ----------------------------------------------------

// The maximum number of users that can be signed in at the same time.
