Mojo module

ffi

Implements a foreign functions interface (FFI).

Aliases

• ​c_char = SIMD[int8, 1]: C char type.
• ​c_double = SIMD[float64, 1]: C double type.
• ​c_float = SIMD[float32, 1]: C float type.
• ​c_int = SIMD[int32, 1]: C int type. The C int type is typically a signed 32-bit integer on commonly used targets today.
• ​c_long = SIMD[_c_long_dtype(), 1]: C long type. The C long type is typically a signed 64-bit integer on macOS and Linux, and a 32-bit integer on Windows.
• ​c_long_long = SIMD[_c_long_long_dtype(), 1]: C long long type. The C long long type is typically a signed 64-bit integer on commonly used targets today.
• ​c_short = SIMD[int16, 1]: C short type.
• ​c_size_t = UInt: C size_t type.
• ​c_ssize_t = Int: C ssize_t type.
• ​c_uchar = SIMD[uint8, 1]: C unsigned char type.
• ​c_uint = SIMD[uint32, 1]: C unsigned int type.
• ​c_ushort = SIMD[uint16, 1]: C unsigned short type.
• ​DEFAULT_RTLD = (256 if os_is_linux() else 8 | 2):
• ​OpaquePointer = UnsafePointer[NoneType]: An opaque pointer, equivalent to the C void* type.

Structs

• ​DLHandle: Represents a dynamically linked library that can be loaded and unloaded.
• ​RTLD: Enumeration of the RTLD flags used during dynamic library loading.

Functions

• ​external_call: Calls an external function.
