  18. .SH DESCRIPTION
  19. Some of the functionality described on this reference page extends the
  20. ISO\ C standard. Applications shall define the appropriate feature test macro
  21. (see the System Interfaces volume of POSIX.1\(hy2017,
  22. .IR "Section 2.2" ", " "The Compilation Environment")
  23. to enable the visibility of these symbols in this header.
  24. .P
  25. The
  26. .IR <setjmp.h> 
  27. header shall define the array types
  28. .BR jmp_buf
  29. and
  30. .BR sigjmp_buf .
  31. .P
  32. The following shall be declared as functions and may also be defined as
  33. macros. Function prototypes shall be provided.
