EOVERFLOW

Data type representability

On Solaris, EOVERFLOW is errno value 79. The base message is value too large to be stored in data type, but the useful diagnostic context is narrower than the short message: Solaris could not store a value in the requested data type without overflow.

Use the Solaris-specific errno table first, then compare with POSIX only for portable behavior. Some Solaris values share names with other UNIX systems but have different numbers or more specific historical meanings.

What to check

Capture the exact interface, structure type, and ABI width used by the process.
for path failures, record both full pathname length and individual component length.
for representability failures, compare large-file, 32-bit, and 64-bit build modes.
