strerror
strerror — retrieves an error message.
Arguments
- errno
The error number as returned by errno.
Returns
An error message as a string.
Description
This function looks up error
messages associated with error numbers.
Example
In this
example, we first define a function to remove a file. Then we call
that function on a non-existing file to generate an error. Finally,
we check the returned error code to get the error message.
function remove_file(file)
{
unlink(file);
errno();
}
Gamma> ret_val = remove_file("/tmp/xyz");
2
Gamma> strerror(2);
"No such file or directory"
