Field Documentation

int(* close)(struct _MG_RWops *context)

Close and free an allocated MG_RWops structure.

Definition at line 105 of file endianrw.h.

int(* eof)(struct _MG_RWops *context)

Test the end-of-file indicator.

Definition at line 110 of file endianrw.h.

int(* read)(struct _MG_RWops *context, void *ptr, int objsize, int num)

Read up to num objects each of size objsize from the data source to the area pointed at by ptr. Returns the number of objects read, or -1 if the read failed.

Definition at line 87 of file endianrw.h.

int(* seek)(struct _MG_RWops *context, int offset, int whence)

Seek to offset relative to whence, one of stdio's whence values:
SEEK_SET, SEEK_CUR, SEEK_END
Returns the final offset in the data source.

Definition at line 80 of file endianrw.h.

Uint32 type

Indicates the type of data source. can be one of the following values:

• RWAREA_TYPE_UNKNOWN
  A unknown (uninitialized) data source type.
• RWAREA_TYPE_STDIO
  Stdio stream data source.
• RWAREA_TYPE_MEM
  Memory data source.

Definition at line 122 of file endianrw.h.

int(* write)(struct _MG_RWops *context, const void *ptr, int objsize, int num)

Write exactly num objects each of size objsize from the area pointed at by ptr to data source. Returns num, or -1 if the write failed.
