dirname
Returns the path up to the last level of a specified string.
string dirname(const char *string)
The dirname
function creates a string that consists of all but the last
level of the path name that's specified by a specified string, string.
The returned string is allocated out of scratch memory and is therefore valid only during
processing of the clause. If insufficient scratch memory is available,
dirname
doesn't run and an error is generated.
Example 7-14 How to use dirname to return the path up to the last element in a string
BEGIN
{
printf("%s\n", dirname("/foo/bar/baz"));
printf("%s\n", dirname("/foo/bar///baz/"));
printf("%s\n", dirname("/foo/bar/baz/"));
printf("%s\n", dirname("/foo/bar/baz//"));
}
Each of these statements renders the output: /foo/bar
.
