This function reads the next Object from a Channel and returns a
pointer to the new Object.
- Synopsis:
AstObject *astRead( AstChannel *this )
- Parameters:
-
this
-
Pointer to the Channel.
- Returned Value:
-
astRead()
-
A pointer to the new Object. The class to which this will

A null Object pointer (AST__NULL) will be returned, without
error, if the Channel contains no further Objects to be read.
-
A null Object pointer will also be returned if this function
is invoked with the AST error status set, or if it should fail
for any reason.
