func ByteSlice ¶

func ByteSlice(name []string) **byte

ByteSlice creates a pointer to a byte slice of C strings This function was copied from purego

func CString ¶

func CString(name string) *byte

CString converts a go string to *byte that can be passed to C code. This function was copied from purego

func GFree ¶

func GFree(ptr uintptr)

GFree frees memory allocated by GLib allocation APIs.

func GFreeNullable ¶

func GFreeNullable(ptr uintptr)

GFreeNullable frees a nullable GLib-allocated pointer.

func GStrdup ¶

func GStrdup(s string) uintptr

GStrdup allocates a C-owned copy of a Go string using g_strdup. The returned pointer must be freed with g_free by the receiver or callee.

func GStrdupNullable ¶

func GStrdupNullable(s *string) uintptr

GStrdupNullable is like GStrdup but accepts a nullable *string.

func GetPaths ¶

func GetPaths(name string) []string

GetPaths gets all shared object files from a library name and panics if no matching library can be found. TODO: Hardcode a library shared object with linker -X flag. This is useful for packaging.

func GoString ¶

func GoString(c uintptr) string

GoString copies a char* to a Go string. This function was copied from purego

func GoStringSlice ¶

func GoStringSlice(c uintptr) []string

GoStringSlice gets a string slice from a char** array This function was copied from purego

func NullableStringToPtr ¶

func NullableStringToPtr(s *string) (uintptr, []byte)

NullableStringToPtr converts a nullable Go string to a C string pointer. The caller must call runtime.KeepAlive(backing) after the C call completes.

func PtrToNullableString ¶

func PtrToNullableString(ptr uintptr) *string

PtrToNullableString converts a nullable char* to a Go *string.

func PuregoSafeRegister ¶

func PuregoSafeRegister(fptr interface{}, libs []uintptr, name string)

func SetPackageName ¶

func SetPackageName(libName, pkgName string)

SetPackageName registers a pkg-config package name for a library. This is used by the code generator to set package names from GIR files. It won't override existing entries to preserve defaults.

func SetSharedLibraries ¶

func SetSharedLibraries(libName string, sharedLibs []string)

SetSharedLibraries registers shared library names for a library. This is used by the code generator to set library names from GIR files. It won't override existing entries to preserve defaults.

func TryGetPaths ¶ added in v0.3.0

func TryGetPaths(name string) []string

TryGetPaths is like GetPaths but returns an empty slice instead of panicking. Use this for optional libraries that may not be installed.
