.TH STR 1
|
||
|
||
.SH NAME
|
||
|
||
str \(en test the character types of string arguments
|
||
|
||
.SH SYNOPSIS
|
||
|
||
str
|
||
.RB [ type ]
|
||
.RB [ string... ]
|
||
|
||
.SH DESCRIPTION
|
||
|
||
Test string arguments.
|
||
|
||
The tests in this program are equivalent to the functions with the same names in
|
||
ctype.h(0p) and are the methods by which string arguments are tested.
|
||
|
||
.SH DIAGNOSTICS
|
||
|
||
If all tests pass, the program will exit with an exit code of 0. If any of the
|
||
tests fail, the program will exit unsuccessfully with an error code of 1.
|
||
|
||
An empty string will cause an unsuccessful exit as none of its contents pass any
|
||
tests.
|
||
|
||
When invoked incorrectly, a debug message will be printed and the program will
|
||
exit with the appropriate sysexits.h(3) error code.
|
||
|
||
.SH BUGS
|
||
|
||
There’s no way of knowing which argument failed the test without re-testing
|
||
arguments individually.
|
||
|
||
If a character in a string isn't valid ASCII str will exit unsuccessfully.
