They make use of the compilation environments declared in ../compilation.cfg, and are processed by the symbols test. We have organized the files by header file, that is the tests for symbols declared in a header file (e.g. appear in a file based on that header file's name (e.g. unistd_h.cfg.) This is purely for convenience. Within these various declarations, we have the following field types: This is a list of compilation environments where the symbol should be legal. To indicate that the symbol must not be legal an environment group can be prefixed with "-". For example, "SUS+ -SUSv4+" indicates a symbol that is legal in all SUS environments up to SUSv3, and was removed in SUSv4 and subsequent versions of SUS. As you can see, we can list multiple environments or environment groups, and we can add or remove to previous groups with subsequent ones. This is a symbol name. It follows the rules for C symbol names.
This is a header file, for example, unistd.h. Conventionally, the header files used should match the file where the test is declared. This is a C type. Function types can be declared without their names, e.g. "void (*)(int)". Structures (e.g. "struct stat") and pointer types (e.g. "pthead_t *") are legal as well. Here are the types of declarations in these files: type | |
| Tests for a C type with . The test verifies that a variable with this type can be declared when the
is included. value | | |
| Tests for a value named , of type . The test attempts to assign the given value to a scratch variable declared with the given type. The value can be a macro or other C symbol. func | | | [; ]... |
| Tests whether a function , returning the first , and taking arguments of following values, is declared. Note that the argument types are separated by semicolons. For varargs style functions, leave out the ... part. For function declarations that have no declared arguments, either void can specified, or the type list can be omitted. Examples: type | size_t | sys/types.h | ALL value | NULL | void * | stdlib.h | ALL func strnlen | int | const char *; int | string.h | ALL
