This file provides a general interface for SDL to read and write data streams. It can easily be extended to files, memory, etc.

void SDL_FreeRW | ( | SDL_RWops * | area | ) |
void* SDL_LoadFile | ( | const char * | file, |
size_t * | datasize | ||

Load an entire file.
The data is allocated with a zero byte at the end (null terminated)
If datasize
is not NULL, it is filled with the size of the data read.
If freesrc
is non-zero, the stream will be closed after being read.
The data should be freed with SDL_free().
Load all the data from an SDL data stream.
The data is allocated with a zero byte at the end (null terminated)
If datasize
is not NULL, it is filled with the size of the data read.
If freesrc
is non-zero, the stream will be closed after being read.
The data should be freed with SDL_free().
int SDL_RWclose | ( | SDL_RWops * | context | ) |
Close and free an allocated SDL_RWops structure.

SDL_RWops* SDL_RWFromMem | ( | void * | mem, |
int | size | ||

Read up to maxnum
objects each of size size
from the data stream to the area pointed at by ptr
.
Seek to offset
relative to whence
, one of stdio's whence values: RW_SEEK_SET, RW_SEEK_CUR, RW_SEEK_END
Return the size of the file in this rwops, or -1 if unknown
Return the current offset in the data stream, or -1 on error.
Write exactly num
objects each of size size
from the area pointed at by ptr
to data stream.
