+# NAME
+
+stralloc.h - heap memory management
+
+# SYNOPSIS
+
+    #include <limb/stralloc.h>
+
+# DESCRIPTION
+
+This header defines functions to work heap-allocated memory.
+
+! INFO: skalibs
+! This header is a complement to skalibs' own [skalibs/stralloc.h](0) and thusly
+! includes said header.
+
+## Functions
+
+The following functions/macros are defined :
+
+: [stralloc_cats0](3)
+:: Appends a string and its NUL-terminating byte into a *stralloc*.
+
+: [stralloc_copys0](3)
+:: Copy a string and its NUL-terminating byte into a *stralloc*.
+
+: [stralloc_inserts0](3)
+:: Insert a string and its NUL-terminating byte into a *stralloc*.

+
+# DESCRIPTION
+
+The `stralloc_catb`() function appends the content of memory pointed by `data`
+of length `dlen` into the stralloc `sa`.
+
+The `stralloc_cats`() function is similar to `stralloc_catb`() but appending
+the NUL-terminated string pointed by `str`, not including said NUL-terminating
+byte.
+
+The `stralloc_cats0`() function is similar to `stralloc_cats`() but including
+the NUL-terminating byte.
+
+The `stralloc_catv`() function is similar to `stralloc_catb`() but gathering the
+data to add from the array of vectors `v` of `n` elements.
+
+The `stralloc_cat`() function is similar to `stralloc_catb`() function but
+appending the content of stralloc `sasce`.
+
+
+The `stralloc_copyb`() function copies the content of memory pointed by `data`
+of length `dlen` into the stralloc `sa`. That is, the stralloc will only contain
+`data` afterwards.
+
+The `stralloc_copys`() function is similar to `stralloc_copyb`() but copying
+the NUL-terminated string pointed by `str`, not including said NUL-terminating
+byte.
+
+The `stralloc_copys0`() function is similar to `stralloc_copys`() but including
+the NUL-terminating byte.
+
+The `stralloc_copy`() function is similar to `stralloc_copyb`() function but
+copying the content of stralloc `sasce`.
+
+
+The `stralloc_insertb`() function inserts the content of memory pointed by
+`data` of length `dlen` into the stralloc `sa` at offset `offset`.
+
+The `stralloc_inserts`() function is similar to `stralloc_insertb`() but
+inserting the NUL-terminated string pointed by `str`, not including said
+NUL-terminating byte.
+
+The `stralloc_inserts0`() function is similar to `stralloc_inserts`() but
+including the NUL-terminating byte.
+
+The `stralloc_insert`() function is similar to `stralloc_insertb`() function but
+inserting the content of stralloc `sasce`.
+
+
+The `stralloc_append`() function appends byte `c` into the stralloc `sa`.
+
+The `stralloc_0`() function appends a NUL-byte into stralloc `sa`.
+
+# RETURN VALUE
+
+These functions return 1 on success. Otherwise they return 0 and set `errno` to
+indicate the error.
+
+# ERRORS
+
+These functions may fail if :
+
+: *ENOMEM*
+:: Out of memory.
+
+The `stralloc_insertb`(), `stralloc_inserts`(), `stralloc_inserts0`() and
+`stralloc_insert`() functions may also fail if :
+
+: *EINVAL*
+:: The `offset` is too high.
