Index: Macros, structures and functions ¶

All Gnuastro library’s exported macros start with GAL_, and its exported structures and functions start with gal_. This abbreviation stands for GNU Astronomy Library. The next element in the name is the name of the header which declares or defines them, so to use the gal_array_fset_const function, you have to #include <gnuastro/array.h>. See Gnuastro library for more. The pthread_barrier constructs are our implementation and are only available on systems that do not have them, see Implementation of pthread_barrier.
