SDL_GetProcessInput - Man Page

#include <SDL3/SDL_process.h>

SDL_IOStream * SDL_GetProcessInput(SDL_Process *process);

The process must have been created with SDL_CreateProcess() and pipe_stdio set to true, or with SDL_CreateProcessWithProperties() and SDL_PROP_PROCESS_CREATE_STDIN_NUMBER set to SDL_PROCESS_STDIO_APP.

Writing to this stream can return less data than expected if the process hasn't read its input. It may be blocked waiting for its output to be read, if so you may need to call SDL_GetProcessOutput() and read the output in parallel with writing input.

process

The process to get the input stream for.

Returns the input stream or NULL on failure; call SDL_GetError() for more information.

It is safe to call this function from any thread.

This function is available since SDL 3.2.0.
