| Summary | 0000383: function with the same name as a special builtin | ||||||
| Description |
The command search in 2.9.1.1 means that a function with the same name as a special builtin (such as export) cannot be called. Section 2.9.5 Function Definition Command allows function definitions to fail with a non-zero exit status but does not specify conditions for this. It does not really make much sense to me to allow defining a function but not calling it. In ksh93, trying to define a function with the same name as a special builtin is a run-time fatal error. In dash, it is a parse error. Therefore, forbidding functions with the same name as a special builtin is existing practice in some implementations. |
||||||
| Desired Action |
Change The function is named fname; the application shall ensure that it is a name (see XBD Section 3.230, on page 70). to The function is named fname; the application shall ensure that it is a name (see XBD Section 3.230, on page 70) and that it does not match the name of a special built-in utility. |
