GETSECTBYNAME

NAME

SYNOPSIS

#include <mach-o/getsect.h>

const struct section *getsectbynamefromheader(
const struct mach_header *mhp,
const char *segname,
const char *sectname)

const struct section *getsectbyname(
const char *segname,
const char *sectname)

char *getsectdatafromheader(
const struct mach_header *mhp,
const char *segname,
const char *sectname,
unsigned long *size)

char *getsectdata(
const char *segname,
const char *sectname,
unsigned long *size)

char *getsectdatafromFramework(
const char *FrameworkName,
const char *segname,
const char *sectname,
unsigned long *size)

DESCRIPTION

Getsectbyname is the same as getsectbynamefromheader with its first argument being the link editor defined symbol _mh_execute_header.

Getsectdatafromheader returns the address to the data for the named section in the named segment if it exists in the specified Mach header. Also it returns the size of the section data indirectly through the pointer size. Otherwise it returns NULL for the pointer and zero for the size. If the specified Mach header comes from a dynamic library as returned by _dyld_get_image_header(3) the address to the data returned will have to have _dyld_get_image_vmaddr_slide(3) added to it to make it a valid pointer.

Getsectdata is the same as getsectdatafromheader with its first argument being the link editor defined symbol _mh_execute_header.

getsectdatafromFramework is used to get the named section data from the named Framework. For example, the framework name ``Appkit'' would be used for /System/Library/Frameworks/Appkit.framework/Versions/C/Appkit. If that Framework isn't being used by the program then it returns NULL for the pointer and zero for the size.
