omp_get_memory¶
View page sourceGet At Least A Specified Amount of Memory¶
Deprecated 2011-08-31¶
Use the function thread_alloc::get_memory instead.
Syntax¶
#
include <cppad/utility/omp_alloc.hpp>
v_ptr = omp_alloc::get_memory ( min_bytes , cap_bytes )
Purpose¶
Use omp_alloc to obtain a minimum number of bytes of memory (for use by the current thread ).
min_bytes¶
This argument has prototype
size_tmin_bytes
It specifies the minimum number of bytes to allocate.
cap_bytes¶
This argument has prototype
size_t&cap_bytes
It’s input value does not matter. Upon return, it is the actual number of bytes (capacity) that have been allocated for use,
min_bytes <= cap_bytes
v_ptr¶
The return value v_ptr has prototype
void* v_ptr
It is the location where the cap_bytes of memory that have been allocated for use begins.
Allocation Speed¶
This allocation should be faster if the following conditions hold:
The memory allocated by a previous call to
get_memoryis currently available for use.The current min_bytes is between the previous min_bytes and previous cap_bytes .
