## Detailed Description

Version information.

Version information may be used to check the library version at compile-time, using macros, or at run-time, using constants.

## Define Documentation

#define STP_BINARY_AGE (0)

#define STP_CHECK_VERSION | ( | major,
|  | minor,
|  | micro |  | ) |

Value:

    (STP_MAJOR_VERSION >  (major) ||                \
      (STP_MAJOR_VERSION == (major) &&              \
       STP_MINOR_VERSION > (minor)) ||              \
      (STP_MAJOR_VERSION == (major) &&              \
       STP_MINOR_VERSION == (minor) &&              \
       STP_MICRO_VERSION >= (micro)))

#define STP_CURRENT_INTERFACE (2)

#define STP_INTERFACE_AGE (0)

#define STP_MAJOR_VERSION (5)

#define STP_MICRO_VERSION (4)

#define STP_MINOR_VERSION (1)

## Function Documentation

const char* stp_check_version | ( | unsigned int | required_major,
|  | unsigned int | required_minor,
|  | unsigned int | required_micro |
| ) |  |  |

Check whether the library provides the requested version.

Parameters:

  | required_major | the minimum major revision.
  | required_minor | the minimum minor revision.
  | required_micro | the minimum micro revision.

Returns:
  NULL if the version matches, or else a description of the error if the library is too old or too new.
