NAME
SDL_GetProcessInput - Get the SDL_IOStream associated with process standard input.
SYNOPSIS
#include <SDL3/SDL_process.h>
SDL_IOStream * SDL_GetProcessInput(SDL_Process *process);
DESCRIPTION
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.
FUNCTION PARAMETERS
process
The process to get the input stream for.
RETURN VALUE
Returns the input stream or NULL on failure; call SDL_GetError() for more information.
THREAD SAFETY
It is safe to call this function from any thread.
AVAILABILITY
This function is available since SDL 3.2.0.
