# NAME
pt_iscache_set_limit - set the mapped image section cache limit
# SYNOPSIS
| **\#include `<intel-pt.h>`**
|
| **int pt_iscache_set_limit(struct pt_image_section_cache \**iscache*,**
| **uint64_t *limit*);**
Link with *-lipt*.
# DESCRIPTION
**pt_iscache_set_limit**() sets the mapped image section cache limit. The
*iscache* argument points to the *pt_image_section_cache* object. The *limit*
argument gives the limit in bytes.
The image section cache will spend at most *limit* bytes to keep image sections
mapped as opposed to mapping and unmapping them when reading from them. This
includes the memory for any caches associated with the mapped section.
A *limit* of zero disables caching and clears the cache.
# RETURN VALUE
**pt_iscache_set_limit**() returns zero on success or a negative *pt_error_code*
enumeration constant in case of an error.
# ERRORS
pte_invalid
: The *iscache* argument is NULL.
# SEE ALSO
**pt_iscache_alloc**(3), **pt_iscache_free**(3), **pt_iscache_read**(3)
