From 58c2577a3ff80e7416ef0434769e2af23365719c Mon Sep 17 00:00:00 2001 From: Alan Modra Date: Wed, 13 Nov 2013 16:55:36 -0500 Subject: This enshrines the current testsuite practice of using ffi_arg for returned values. It would be reasonable and logical to use the actual return argument type as passed to ffi_prep_cif, but this would mean changing a large number of tests that use ffi_arg and all backends that write results to an ffi_arg. --- doc/libffi.texi | 9 +++++---- 1 file changed, 5 insertions(+), 4 deletions(-) (limited to 'doc/libffi.texi') diff --git a/doc/libffi.texi b/doc/libffi.texi index eca11dc..d13c5c0 100644 --- a/doc/libffi.texi +++ b/doc/libffi.texi @@ -214,7 +214,7 @@ int main() ffi_type *args[1]; void *values[1]; char *s; - int rc; + ffi_arg rc; /* Initialize the argument info vectors */ args[0] = &ffi_type_pointer; @@ -222,7 +222,7 @@ int main() /* Initialize the cif */ if (ffi_prep_cif(&cif, FFI_DEFAULT_ABI, 1, - &ffi_type_uint, args) == FFI_OK) + &ffi_type_sint, args) == FFI_OK) @{ s = "Hello World!"; ffi_call(&cif, puts, &rc, values); @@ -414,6 +414,7 @@ Here is the corresponding code to describe this struct to int i; tm_type.size = tm_type.alignment = 0; + tm_type.type = FFI_TYPE_STRUCT; tm_type.elements = &tm_type_elements; for (i = 0; i < 9; i++) @@ -540,7 +541,7 @@ A trivial example that creates a new @code{puts} by binding #include /* Acts like puts with the file given at time of enclosure. */ -void puts_binding(ffi_cif *cif, unsigned int *ret, void* args[], +void puts_binding(ffi_cif *cif, ffi_arg *ret, void* args[], FILE *stream) @{ *ret = fputs(*(char **)args[0], stream); @@ -565,7 +566,7 @@ int main() /* Initialize the cif */ if (ffi_prep_cif(&cif, FFI_DEFAULT_ABI, 1, - &ffi_type_uint, args) == FFI_OK) + &ffi_type_sint, args) == FFI_OK) @{ /* Initialize the closure, setting stream to stdout */ if (ffi_prep_closure_loc(closure, &cif, puts_binding, -- cgit v1.2.1
