Detailed Description

Macro Definition Documentation

vc_libvclinux_check_header_ver

#define vc_libvclinux_check_header_ver

(

)

vc_libvclinux_check_header_ver_func(LIBVCLINUX_MAINVERSION,LIBVCLINUX_VERSION,LIBVCLINUX_SUBVERSION)

This macro compares the version information at the header used at compile time with the version of the library linked at compile time. If the header used is incompatible with the library linked against, this macro returns an error.

Return values

-1	if Main Version of Library differs from the Header's Main Version (General Incompatibility).
+1	if Version of Library is smaller than the Header's Version (Features may be missing).
0	else.

vc_libvcimgnet_check_header_ver

#define vc_libvcimgnet_check_header_ver

vc_libvcimgnet_check_header_ver_func(LIBVCIMGNET_MAINVERSION,LIBVCIMGNET_VERSION,LIBVCIMGNET_SUBVERSION)

This macro compares the version information at the header used at compile time with the version of the library linked at compile time. If the header used is incompatible with the library linked against, this macro returns an error.

Return values

-1	if Main Version of Library differs from the Header's Main Version (General Incompatibility).
+1	if Version of Library is smaller than the Header's Version (Features may be missing).
0	else.
