memset(CountryName, 0, strlen(CountryName)+1);
CountryName = SOME VALUE
Now how do i free the memory after use of this code???? :confused: (3 Replies)
Linux Kernels 2.6.16 and up provide a way to instruct the kernel to drop the page cache, inode and dentry caches on command. This tip can help free Linux memory without a reboot.
Note: This is a non-destructive operation. Dirty objects are not freeable, hence; you must run sync beforehand.

Hi guys.
I've a question, if we are using a syscall that receives a string allocated dynamicaly to a determined size, or NUL and it will allocate the apropriate size. We should free the memory or the OS will do it for us?
If a function returns a pointer we should free that poiter when we are done... (7 Replies)

papi_library_init
PAPI_library_init(3) PAPI PAPI_library_init(3)NAME
PAPI_library_init -
initialize the PAPI library.
SYNOPSIS Detailed Description
@param version
upon initialization, PAPI checks the argument against the internal
value of PAPI_VER_CURRENT when the library was compiled.
This guards against portability problems when updating the PAPI shared
libraries on your system.
@retval PAPI_EINVAL
papi.h is different from the version used to compile the PAPI library.
@retval PAPI_ENOMEM
Insufficient memory to complete the operation.
@retval PAPI_ECMP
This component does not support the underlying hardware.
@retval PAPI_ESYS
A system or C library call failed inside PAPI, see the errno variable.
PAPI_library_init() initializes the PAPI library.
PAPI_is_initialized() check for initialization.
It must be called before any low level PAPI functions can be used.
If your application is making use of threads PAPI_thread_init must also be
called prior to making any calls to the library other than PAPI_library_init() .
@par Examples:
* int retval;
* retval = PAPI_library_init(PAPI_VER_CURRENT);
* if (retval != PAPI_VER_CURRENT && retval > 0) {
* fprintf(stderr,"PAPI library version mismatch!
");
* exit(1); }
* if (retval < 0)
* handle_error(retval);
* retval = PAPI_is_initialized();
* if (retval != PAPI_LOW_LEVEL_INITED)
* handle_error(retval)
*
