Summary

The FILENAME_SCAN_ procedure checks for valid file-name syntax and returns the

length in bytes of that part of the input string that constitutes a file name. Node names

are accepted as valid input, as are partially or fully qualified names of disk files,

processes, and devices. File-name patterns and subvolume names are accepted

when you select the appropriate options. FILENAME_SCAN_ checks syntax only; no

check for the existence of any entity is performed.

Refer to Appendix D, File Names and Process Identifiers

for the definitions of file name

and file-name pattern.
