GETSEGBYNAME(3)                                                                              GETSEGBYNAME(3)



NAME
       getsegbyname - get the segment command for the named segment

SYNOPSIS
       #include <mach-o/getsect.h>

       const struct segment_command *getsegbyname(const char *segname);

DESCRIPTION
       This  routine  returns the segment_command structure for the named segment if it exists in the Mach-O
       (Mach object) executable getsegbyname(3) is linked into.  Otherwise getsegbyname(3) returns NULL.  It
       uses  the  link  editor  defined  symbol _mh_execute_header and just looks through the load commands.
       Since these are mapped into the __TEXT segment they are read-only and thus const by default.  If this
       is   to   be   used  in  executables  linked  with  -pie  then  the  value  return  by  the  call  to
       _dyld_get_image_vmaddr_slide(0) will need to be added to the  vmaddr  field  of  the  segment_command
       struct.
