Why use GLib functions?

Question

While programming in C and GTK+, why is it \"better\" to use g_strdup_printf, g_free, g_strcmp0 etc... and fellow GLib functions?

Answer 1

Here is an update. It looks the developer's realized their mistake:

g_mem_is_system_malloc has been deprecated since version 2.46 and should not be used in newly-written code.

GLib always uses the system malloc, so this function always returns TRUE.

Checks whether the allocator used by g_malloc() is the system's malloc implementation. If it returns TRUE memory allocated with malloc() can be used interchangeable with memory allocated using g_malloc(). This function is useful for avoiding an extra copy of allocated memory returned by a non-GLib-based API.
