Detailed Description
Typedefs for the library datatypes and related symbolic constants.
The datatypes provided by the library should be manipulated by means of the corresponding opaque pointer types and the functions working on them.
- Note
- To simplify the detection of common programming mistakes, we provide both pointer-to-const and pointer-to-nonconst opaque pointers, with implicit conversions mapping each pointer-to-nonconst to the corresponding pointer-to-const when needed. The user of the C interface is therefore recommended to adopt the pointer-to-const type whenever read-only access is meant.
Typedef Documentation
| typedef const char* ppl_io_variable_output_function_type(ppl_dimension_type var) |
The type of output functions used for printing variables.
An output function for variables must write a textual representation for var to a character buffer, null-terminate it, and return a pointer to the beginning of the buffer. In case the operation fails, 0 should be returned and perhaps errno should be set in a meaningful way. The library does nothing with the buffer, besides printing its contents.

Utility function for the wrapping of lines of text.
- Parameters
-
src The source string holding the text to wrap. indent_depth The indentation depth. preferred_first_line_length The preferred length for the first line of text. preferred_line_length The preferred length for all the lines but the first one.
- Returns
- The wrapped string in a malloc-allocated buffer.
