Differences between glib and glibc

When I installed syslog-ng 3.0 today, I said that glib 2.12.3 or above is required. I think there is another glibc library, which seems to be different. I searched the internet for it:

Glib is GTK
+ The Basics of libraries and gnome. Glib can be used on multiple platforms, such as Linux, UNIX, and windows. Glib provides substitutes for many standard and common C language structures.
Glib defines a lot of useful data structures, such as single (dual) connected tables, variable length arrays, thread pools, and other useful things. Use the glib LibraryProgramShould contain the glib header file glib. h.

Glibc
Is a C library that provides system calls and basic functions, such as open, malloc, and printf. All programs with dynamic connections need to use it. Is the C library developed by GNU.

They do not have much to do with their purposes.

Glib is a general-purpose Utility library, which provides implements useful data
Types, macros, type conversions, string utilities, file utilities, a main loop
Invalid action, and so on. It works on customized Unix-like platforms, windows, OS/2 and
BEOs. glib is released under the GNU Library General Public License (GNU
Lgpl ).

The general policy of glib is that all functions are invisibly threadsafe
With the exception of Data Structure manipulation functions, where, if you have
Two threads manipulating the same data structure, they must use a lock
Synchronize their operation.

Glibc

The gnu c library is primarily designed to be a portable and High Performance
C library.

It follows all relevant standards (ISO c 99, posix.1c, posix.1j, posix.1d,
Unix98, single UNIX Specification). It is also internationalized and has one
The most complete internationalization interfaces known.
