## 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.

## Macro Definition Documentation

#define STP_BINARY_AGE (4)

#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)))

## 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.
