SDL_ReadProcess - Read all the output from a process.

       This function is available since SDL 3.2.0.

       If  a  process  was created with I/O enabled, you can use this function to read the output. This function
       blocks until the process is complete, capturing all output, and providing the process exit code.

       The data is allocated with a zero byte at the end (null terminated) for convenience. This extra  byte  is
       not included in the value reported via datasize.

       The data should be freed with SDL_free().

process

       datasize
              a pointer filled in with the number of bytes read, may be NULL.

       exitcode
              a pointer filled in with the process exit code if the process has exited, may be NULL.
