$ x=für
$ print ${#x}

Is there an easy way to get the length of a... (8 Replies)

unsetenv
setenv(3C)setenv(3C)NAME
setenv(), unsetenv() - add, update or remove an environment variable
SYNOPSIS
Parameters
envname Points to a string containing the name of an environment variable to be added or altered. This should not be a NULL
pointer or null string, and the string should not contain an equal character.
envval Points to a string containing the value to be set for the variable envname.
overwrite Indicates whether to overwrite the value of envname variable or not, if it already exists. Expected values are non-zero
and zero. If the environment variable does not exist in the environment, then the value of this variable is ignored.
DESCRIPTION
and functions update the environment of the calling process.
If envname does not exist, the function ignores the value of overwrite and adds the variable envname to the environment with the value
envval. If envname exists and overwrite is non-zero, then the variable envname is updated with the new value envval. If envname exists
and overwrite is zero, then the variable is not updated, and the function is considered to have completed successfully.
The function deletes the variable envname from the environment, if it exists. If the envname variable does not exist in the current envi-
ronment, the environment is unchanged, and the function is considered to have completed successfully.
If the application modifies environ or the pointers to which it points, the behavior of and is undefined.
EXTERNAL INFLUENCES
Locale
The category determines the interpretation of characters in string as single- and/or multi-byte characters.
International Code Set Support
Single- and multi-byte character code sets are supported.
RETURN VALUE
The and functions return zero on success; otherwise they return and set to indicate the error.
ERRORS
If the function fails, is set to one of the following values:
Sufficient memory is not available to add a variable or its value to
the environment.
The envname argument is a null pointer, points to an empty string, or points to a string containing an equal character.
If the function fails, is set to the following value:
The envname argument is a null pointer, points to an empty string, or points to a string containing an equal character.
EXAMPLES
The following code adds a new environment variable to the current environment.
The following code updates the variable
The following code removes the variable from the current environment.
WARNINGS
The and functions manipulate the environment pointed to by environ, and can be used in conjunction with However, envp (the third argument
to main) is not changed.
The uses to enlarge the environment (see malloc(3C)).
After the or function is called, environment variables may not be in alphabetical order.
