| Summary | 0000808: getgrgid() missing requirement not to change errno | ||||||
| Description |
The application usage for getgrgid() advises that applications should set errno to zero before the call in order to distinguish between the "not found" case and an error. However, there is no requirement in normative text that getgrgid() does not change errno for the "not found" case. The same applies to getgrnam(). For getpwnam() and getpwuid() the situation is a little different because the advice to application writers about setting errno to zero appears in normative text and clearly implies that errno is not changed for the "not found" case. However, it would be better still if this was stated directly. |

On page 1023 line 34587 section getgrgid, page 1027 line 34718 section getgrnam, page 1065 line 35887 section getpwnam, page 1069 line 36023 section getpwuid change: On error, errno shall be set to indicate the error. to: If the requested entry was not found, errno shall not be changed. On error, errno shall be set to indicate the error. After page 1023 line 34576 section getgrgid add a new paragraph: Applications wishing to check for error situations should set errno to 0 before calling getgrgid(). If getgrgid() returns a null pointer and errno is set to non-zero, an error occurred. On page 1025 line 34652 section getgrgid delete: Applications wishing to check for error situations should set errno to 0 before calling getgrgid(). If errno is set on return, an error occurred. After page 1027 line 34707 section getgrnam add a new paragraph: Applications wishing to check for error situations should set errno to 0 before calling getgrnam(). If getgrnam() returns a null pointer and errno is set to non-zero, an error occurred. On page 1028 line 34769 section getgrnam delete: Applications wishing to check for error situations should set errno to 0 before calling getgrnam(). If errno is set on return, an error occurred. |

Interpretation response ------------------------ The standard does not speak to this issue, and as such no conformance distinction can be made between alternative implementations based on this. This is being referred to the sponsor. Rationale: ------------- Application developers requiring to check for errors from these functions should set errno to zero before calling the function if they need to determine if an error occurred. Notes to the Editor (not part of this interpretation): ------------------------------------------------------- See desired action. |
