NOTES
On systems running H06.24 or later H-series RVUs or J06.13 or later J-series RVUs, you can use
this function with 32-bit or 64-bit OSS applications.
RETURN VALUES
Upon successful completion, the fpathconf() function returns the specified parameter. Other-
wise, the value -1 is returned and errno is set to indicate the error. The value -1 is returned, with
errno unchanged, if the variable corresponding to name has no limit for the path or file descrip-
tor.
The fpathconf() function returns the value -1 and sets errno if one or more of the following are
true:
• Your system needs to use the filedes parameter to determine the value of name, but your
system does not allow name to be associated with the file specified by filedes.
• The process does not have appropriate privilege to access the file specified by filedes.
• filedes is invalid.
ERRORS
If any of the following conditions occurs, the fpathconf() function sets errno to the correspond-
ing value:
[EBADF] The filedes parameter is not a valid file descriptor.
[EFSBAD] The program attempted an operation involving a fileset with a corrupted fileset
catalog.
