nyx_memory_alloc
__NYX_NULLABLE__ buff_t nyx_memory_alloc(__NYX_ZEROABLE__ size_t size)
Similar to libc malloc except that a memory overflow causes the node to stop.
nyx_memory_free
__NYX_ZEROABLE__ size_t nyx_memory_free(__NYX_NULLABLE__ buff_t buff)
Similar to libc free except that it returns the amount of memory freed.
nyx_string_dup
__NYX_NULLABLE__ str_t nyx_string_dup(__NYX_NULLABLE__ STR_t s)
Similar to libc strdup.
str_t
#define str_t
Alias for char *.
