Crate solana_cpi

Cross-program invocation.

Solana programs may call other programs, termed cross-program invocations (CPI), with the invoke and invoke_signed functions.

This crate does not support overwriting syscall stubs for offchain code. If you want to overwrite syscall stubs, use the wrapper functions in solana_program::program.
