+# NAME
+
+pt_iscache_alloc, pt_iscache_free, pt_iscache_name - allocate/free a traced memory
+image section cache
+
+
+# SYNOPSIS
+
+| **\#include `<intel-pt.h>`**
+|
+| **struct pt_image_section_cache \*pt_iscache_alloc(const char \**name*);**
+| **const char \*pt_iscache_name(const struct pt_image_section_cache \**iscache*);**
+| **void pt_iscache_free(struct pt_image_section_cache \**iscache*);**
+
+Link with *-lipt*.
+
+
+# DESCRIPTION
+
+**pt_iscache_alloc**() allocates a new *pt_image_section_cache* and returns a
+pointer to it.  A *pt_image_section_cache* object contains a collection of file
+sections and the virtual addresses at which those sections were loaded.
+
+The image sections can be added to one or more *pt_image* objects.  The
+underlying file sections will be mapped once and their content will be shared
+across images.
+
+The *name* argument points to an optional zero-terminated name string.  If the
+*name* argument is NULL, it will be ignored and the returned
+*pt_image_section_cache* object will not have a name.  Otherwise, the returned
+*pt_image_section_object* object will have a copy of the string pointed to by
+the *name* argument as name.
+
+**pt_iscache_name**() returns the name of the *pt_image_section_cache* object
+the *iscache* argument points to.
+
+**pt_iscache_free**() frees the *pt_image_section_cache* object pointed to by
+*iscache*.  The *iscache* argument must be NULL or point to an image section
+cache that has been allocated by a call to **pt_iscache_alloc**().
+
+
+# RETURN VALUE
+
+**pt_iscache_alloc**() returns a pointer to a *pt_image_section_cache* object
+on success or NULL in case of an error.
+
+**pt_iscache_name**() returns a pointer to a zero-terminated string of NULL if the
+image section cache does not have a name.
+
+
+# EXAMPLE
+
+~~~{.c}
+int foo(const char *name) {
+    struct pt_image_section_cache *iscache;
+    errcode;
+
+    image = pt_iscache_alloc(name);
+    if (!iscache)
+        return pte_nomem;
+
+    errcode = bar(iscache);
+
+    pt_iscache_free(iscache);
+    return errcode;
+}
