Detailed Description

Errors and failures are indicated in several different ways throughout libNFSNapi, such as returning NULL, or a non-zero value. To determine the precise nature of the error, an error code is often available, either as a return value from a function, or via libnfsnapi_mgr_error.

These error codes always reference a member of the libnfsnapi_error_t enumeration; they can be turned into human-readable messages by using the libnfsnapi_strerror function.
