C++ (Cpp) lobject_read Examples

Example #1

static PyObject *

{
    PyObject *res;
    int where, end, size = -1;
    char *buffer;

    if (!PyArg_ParseTuple(args, "|i", &size)) return NULL;

    EXC_IF_LOBJ_CLOSED(self);
    EXC_IF_LOBJ_LEVEL0(self);
    EXC_IF_LOBJ_UNMARKED(self);

    if (size < 0) {
        if ((where = lobject_tell(self)) < 0) return NULL;
        if ((end = lobject_seek(self, 0, SEEK_END)) < 0) return NULL;
        if (lobject_seek(self, where, SEEK_SET) < 0) return NULL;
        size = end - where;
    }

    if ((buffer = PyMem_Malloc(size)) == NULL) {
        PyErr_NoMemory();
        return NULL;
    }
    if ((size = lobject_read(self, buffer, size)) < 0) {
        PyMem_Free(buffer);
        return NULL;
    }

    res = PyString_FromStringAndSize(buffer, size);
    PyMem_Free(buffer);
