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 seg‐
ment if it exists in the Mach-O (Mach object) executable getsegby‐
name(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 seg‐
ment 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.
