@brief Interfaces for getopt() and getopt_long() work-alike functions.
|
|
|
|
This code was taken from FreeBSD and slightly modified, mostly to rename
|
|
symbols with external linkage to avoid naming conflicts in systems where
|
|
there are real getopt()/getopt_long() implementations. Changed to use
|
|
fixed-width types to allow code using these interfaces to be consistent
|
|
with the rest of the product.
