+random.h - getting pseudo-random data
+
+
+# SYNOPSIS

+    #include <limb/random.h>
+
+
+# DESCRIPTION

+
+## Functions
+
+The following functions/macros are defined :
+
+: [random_buf](3)

+% limb manual
+% random_buf(3)
+
+# NAME
+
+random_buf, random_name
+
+# SYNOPSIS
+
+    #include <limb/random.h>
+
+```pre hl
+void random_buf(char *dst, size_t dlen)
+void random_name(char *dst, size_t dlen)
+```
+
+# DESCRIPTION
+
+The `random_buf`() function will write `dlen` bytes of pseudo-random data into
+the memory pointed by `dst`.
+
+The `random_name`() macro is similar to `random_buf`() except it will ensure all
+written bytes are actually ASCII printable characters, thus forming a valid file
+name (that won't contain any slashes (`/`) nor dots (`.`)).
