Function patch_seq_file_slurp 

#[unsafe(no_mangle)]
pub unsafe extern "C" fn patch_seq_file_slurp(stack: Stack) -> Stack

Read entire file contents as a string

Stack effect: ( String – String )

Takes a file path, reads the entire file, and returns its contents. Panics if the file cannot be read (doesn’t exist, no permission, not UTF-8, etc.)

Safety

• stack must be a valid, non-null stack pointer with a String value on top
• Caller must ensure stack is not concurrently modified
