NAME
libssh2_version - return the libssh2 version number
SYNOPSIS
#include <libssh2.h>
const char *
libssh2_version(int required_version);
DESCRIPTION
If required_version is lower than or equal to the version number of the libssh2 in use, the version number of libssh2 is returned as a pointer to a null-terminated string.
The required_version should be the version number as constructed by the LIBSSH2_VERSION_NUM define in the libssh2.h public header file, which is a 24 bit number in the 0xMMmmpp format. MM for major, mm for minor and pp for patch number.
RETURN VALUE
The version number of libssh2 is returned as a pointer to a null-terminated string or NULL if the required_version is not fulfilled.
EXAMPLE
To make sure you run with the correct libssh2 version:
if(!libssh2_version(LIBSSH2_VERSION_NUM)) {
fprintf(stderr, \&"Runtime libssh2 version too old.\&");
return -1; /* return error */
}
Unconditionally get the version number:
printf(\&"libssh2 version: %s\&", libssh2_version(0));
AVAILABILITY
This function was added in libssh2 1.1, in previous versions there way no way to extract this info in runtime.
