+# NAME
+
+stralloc\_remove - remove data from a stralloc
+
+# SYNOPSIS
+
+    #include <limb/stralloc.h>
+
+```pre hl
+int stralloc_remove(stralloc *<em>sa</em>, size_t <em>offset</em>, size_t <em>len</em>)
+```
+
+# DESCRIPTION
+
+The `stralloc_remove`() function removes data from the stralloc `sa` starting at
+byte `offset` and for `len` bytes.
+
+The member `len` will be adjusted and data afterwards moved as needed, but no
+re-allocation occurs.
+
+# RETURN VALUE
+
+The `stralloc_remove`() function return 1 on success. Otherwise they return 0
+and set `errno` to indicate the error.
+
+# ERRORS
+
+The `stralloc_remove`() function may fail if :
+
+: *EINVAL*
+:: The `offset` is too high.
+
+# SEE ALSO
