Write to an SDL_IOStream data stream.
Defined in <SDL3/SDL_iostream.h>
size_t SDL_WriteIO(SDL_IOStream *context, const void *ptr, size_t size);
SDL_IOStream * | context | a pointer to an SDL_IOStream structure. |
const void * | ptr | a pointer to a buffer containing data to write. |
size_t | size | the number of bytes to write. |
(size_t) Returns the number of bytes written, which will be less than size
on failure; call SDL_GetError() for more information.
This function writes exactly size
bytes from the area pointed at by ptr
to the stream. If this fails for any reason, it'll return less than size
to demonstrate how far the write progressed. On success, it returns size
.
On error, this function still attempts to write as much as possible, so it might return a positive value less than the requested write size.
The caller can use SDL_GetIOStatus() to determine if the problem is recoverable, such as a non-blocking write that can simply be retried later, or a fatal error.
This function is available since SDL 3.0.0.
