◆ xmlSetGenericErrorFunc()

void xmlSetGenericErrorFunc ( void ctx,
xmlGenericErrorFunc  handler 
)

xmlSetGenericErrorFunc: @ctx: the new error handling context @handler: the new handler function

Function to reset the handler and the error context for out of context error messages. This simply means that @handler will be called for subsequent error messages while not parsing nor validating. And @ctx will be passed as first argument to @handler One can simply force messages to be emitted to another FILE * than stderr by setting @ctx to this file handle and @handler to NULL. For multi-threaded applications, this must be set separately for each thread.
