+
+# NAME
+
+siovec.h - manipulating struct iovec
+
+
+# SYNOPSIS
+
+    #include <limb/siovec.h>
+
+
+# DESCRIPTION
+
+The header defines the needed functions to manipulate `struct iovec` containing
+range of bytes in similar manner as byte arrays.
+
+It also defines macros offering a slightly different interface, to remain
+consistent within limb.
+
+! INFO: skalibs
+! This header is a complement to skalibs' own [skalibs/siovec.h](0) and thusly
+! includes said header.
+
+## Functions
+
+The following functions/macros are defined :
+
+: [siov_len](3)
+:: Same as [siovec_len](3)
+
+: [siov_gather](3)
+:: Same as [siovec_gather](3) but with destination as first arguments
+
+: [siov_scatter](3)
+:: Same as [siovec_scatter](3)
+
+: [siov_deal](3)
+:: Same as [siovec_deal](3) but with destination as first arguments
+
+: [siov_seek](3)
+:: Same as [siovec_seek](3)
+
+: [siov_trunc](3)
+:: Same as [siovec_trunc](3)
+
+: [siov_bytechr](3)
+:: Same as [siovec_bytechr](3)
+
+: [siov_bytein](3)
+:: Same as [siovec_bytein](3)
+
+: [siov_seek_gather](3)
+:: Same as [siovec_seek_gather](3) but with destination as first arguments
+
+: [siov_seek_bytechr](3)
+:: Same as [siovec_seek_bytechr](3)
+
+: [siov_seek_bytein](3)
+:: Same a [siovec_seek_bytein](3)
+
+: [siovec_seek_gather](3)
+:: Same as [siovec_gather](3) but from a given offset
+
+: [siovec_seek_bytechr](3)
+:: Same as [siovec_bytechr](3) but from a given offset
+
+: [siovec_seek_bytein](3)
+:: Same as [siovec_bytein](3) but from a given offset

+
+# NAME
+
+siovec\_seek\_bytechr - scan data from *struct iovec* for a given byte
+
+# SYNOPSIS
+
+    #include <limb/siovec.h>
+
+```pre hl
+size_t siovec_seek_bytechr(const struct iovec *<em>v</em>, unsigned int <em>n</em>, size_t <em>offset</em>, char <em>c</em>)
+```
+
+# DESCRIPTION
+
+The `siovec_seek_bytechr`() function scans data pointed by the array `v` of `n`
+*struct iovec* for the first instance of `c`, starting at byte `offset` within
+the data.
+
+This is the equivalent of [siovec_bytechr](3) but skipping the first `offset`
+bytes of data.
+
+# RETURN VALUE
+
+`siovec_seek_bytechr`() returns the position of the first occurrence of `c`
+within the data behind `v` if found. Otherwise it returns the total length of
+the data.
