VALLOC(3C)                                                          VALLOC(3C)



NAME
       valloc - aligned memory allocator

SYNOPSIS
       char *valloc(size)
       unsigned size;

DESCRIPTION
       Valloc  is  obsoleted  by  the  current version of malloc, which aligns
       page-sized and larger allocations.

       _V_a_l_l_o_c allocates _s_i_z_e bytes aligned on a page boundary.  It  is  imple‐
       mented  by calling _m_a_l_l_o_c(3) with a slightly larger request, saving the
       true beginning of the block allocated, and returning a properly aligned
       pointer.

DIAGNOSTICS
       _V_a_l_l_o_c returns a null pointer (0) if there is no available memory or if
       the arena has been detectably corrupted by storing outside  the  bounds
       of a block.

BUGS
       _V_f_r_e_e isn’t implemented.
