SNOBOL4FFI(3) CSNOBOL4 Manual SNOBOL4FFI(3) NAME snobol4ffi - Foreign Function Interface for SNOBOL4 SYNOPSYS -INCLUDE 'ffi.sno' dl = FFI_DLOPEN("/usr/lib/libm.so") sym = FFI_DLSYM(dl, "hypot") DEFINE_FFI("hypot(double,double)double", sym) OUTPUT = hypot(3, 4) DESCRIPTION FFI_DLOPEN(filename) takes the path of a dynamicly loadable executable file and returns a value which can be passed to FFI_DLSYM(). FFI_DLSYM(library,function) takes a library value returned by FFI_DLOPEN(), and a function name, and returns a value which can be passed to DEFINE_FFI(). DEFINE_FFI(prototype,pointer) defines a SNOBOL4 function that calls an external function via ffi(3). prototype contains a string name for the function followed by a comma separated list of parameter types inside of parenthesis (any of: sint8, sint16, sint32, sint64, uint8, uint16, uint32, uint64, schar, sshort, sint, slong, uchar, ushort, uint, ulong, float, double, longdouble, pointer), followed by a return type, which can be any of the above pa- rameter types, or void, string, freestring. pointer is a value re- turned by FFI_DLSYM().
