// Parameters for get_hostfxr_path
//
// Fields:
// size
// Size of the struct. This is used for versioning.
//
// assembly_path
// Path to the compenent's assembly.
// If specified, hostfxr is located as if the assembly_path is the apphost
//
// dotnet_root
// Path to directory containing the dotnet executable.
// If specified, hostfxr is located as if an application is started using
// 'dotnet app.dll', which means it will be searched for under the dotnet_root
// path and the assembly_path is ignored.
//
struct get_hostfxr_parameters {

//
// Get the path to the hostfxr library
//
// Parameters:
// buffer
// Buffer that will be populated with the hostfxr path, including a null terminator.
//
// buffer_size
// [in] Size of buffer in char_t units.
// [out] Size of buffer used in char_t units. If the input value is too small
// or buffer is nullptr, this is populated with the minimum required size
// in char_t units for a buffer to hold the hostfxr path
//
// get_hostfxr_parameters
// Optional. Parameters that modify the behaviour for locating the hostfxr library.
// If nullptr, hostfxr is located using the enviroment variable or global registration
//
// Return value:
// 0 on success, otherwise failure
// 0x80008098 - buffer is too small (HostApiBufferTooSmall)
//
// Remarks:
// The full search for the hostfxr library is done on every call. To minimize the need
// to call this function multiple times, pass a large buffer (e.g. PATH_MAX).
