.TH STR 1 2024-06-17 "Bonsai Core Utilites 0.13.9"
.SH NAME
str \(en test string arguments
.\"
.SH SYNOPSIS

str
.RB [ type ]
.RB [ string... ]
.\"
.SH DESCRIPTION

Test the character types of string arguments.

The tests in this program are equivalent to the functions with the same names in
.BR ctype.h (0p)
and are the methods by which string arguments are tested.
.\"
.SH DIAGNOSTICS

If all tests pass, the program will exit successfully. If any of the tests fail,
the program will exit unsuccessfully with an error code of 1.

When invoked incorrectly, a debug message will be printed and the program will
exit with the appropriate
.BR sysexits.h (3)
error code.
.\"
.SH CAVEATS

None of an empty string\(cqs contents pass any of the tests, so the program will
exit unsuccessfully if one is specified.

There\(cqs no way of knowing which argument failed the test without re-testing
arguments individually.

If a character in a string isn\(cqt valid ASCII, the program will exit
unsuccessfully.
