NAME

       SDL_ReadIO - Read from a data source.

SYNOPSIS

       #include <SDL3/SDL_iostream.h>

       size_t SDL_ReadIO(SDL_IOStream *context, void *ptr, size_t size);

DESCRIPTION

       This  function reads up size bytes from the data source to the area pointed at by ptr.  This function may
       read less bytes than requested.

       This function will return zero when the data stream is completely read, and SDL_GetIOStatus() will return
       SDL_IO_STATUS_EOF.  If zero is returned and the stream is not at EOF,  SDL_GetIOStatus()  will  return  a
       different error value and SDL_GetError() will offer a human-readable message.

FUNCTION PARAMETERS

       context
              a pointer to an SDL_IOStream structure.

       ptr    a pointer to a buffer to read data into.

       size   the number of bytes to read from the data source.

RETURN VALUE
