Typedefs

typedef int (*xmlInputCloseCallback) (
    void *context);  

Discussion

xmlInputCloseCallback: @context: an Input context

Callback used in the I/O Input API to close the resource

Returns 0 or -1 in case of error

typedef int (*xmlInputMatchCallback) (
    char const *filename);  

Discussion

xmlInputMatchCallback: @filename: the filename or URI

Callback used in the I/O Input API to detect if the current handler can provide input fonctionnalities for this resource.

Returns 1 if yes and 0 if another Input module should be used

typedef void * (*xmlInputOpenCallback) (
    char const *filename);  

Discussion

xmlInputOpenCallback: @filename: the filename or URI

Callback used in the I/O Input API to open the resource

Returns an Input context or NULL in case or error

typedef int (*xmlInputReadCallback) (
    void *context,
    char *buffer,
    int len);  

Discussion
