|
| + * This header file exports the API to the NSPR portable library or string-
|
| + * handling functions.
|
| + *
|
| + * This API was not designed as an "optimal" or "ideal" string library; it
|
| + * was based on the good ol' unix string.3 functions, and was written to
|
| + *
|
| + * 1) replace the libc functions, for cross-platform consistency,
|
| + * 2) complete the API on platforms lacking common functions (e.g.,
|
| + * strcase*), and
|
| + * 3) to implement some obvious "closure" functions that I've seen
|
| + * people hacking around in our code.
|
| + *
|
| + * Point number three largely means that most functions have an "strn"
|
| + * limited-length version, and all comparison routines have a non-case-
|
| + * sensitive version available.
