10. A computer-implemented method for facilitating a single interface for file I/O and network communication, the method comprising: receiving, by a content producing device from a local application, a first command to create content, wherein the first command includes a name for the content and access control information that indicates how the content may be accessed, wherein the content name is a hierarchically structured variable length identifier that includes contiguous name components ordered from a most general level to a most specific level; creating a first manifest which is a content object that indicates a set of member content objects by a name and a digest, wherein a name for the first manifest is the content name corresponding to the first command, wherein access to the manifest is based on the access control information included in the first command; and transmitting to the local application the first manifest and an indicator of success for creating the first manifest, thereby facilitating an interface for the local application to process network data in a content centric network; wherein the method is performed by a component that serves as an interface between the local application and a portal instance associated with a transport stack, and wherein the component, the local application, and the transport stack reside on the content producing device.
11. The method of claim 10 , further comprising: receiving from the local application a second command to update the content with new data, wherein the second command includes the first manifest name or a name of a member content object as indicated in the first manifest, a buffer which contains the new data for the update, a count for subsequent use in indicating a successful update, and an offset within the first manifest or within the member content object from which the new data is to be written; updating the first manifest or the member content object by writing the new data in the buffer to the first manifest or the member content object starting from the offset; and returning the count to the local application.
