Hi, I am currently working on a driver and have been utilizing CPL_calloc(). However, when attempting to pass the Actions, I encounter errors such as:
warning C4244: 'function': conversion from 'MM_INTERNAL_FID' to 'size_t', possible loss of data This issue can be addressed by casting 'MM_INTERNAL_FID' (which is a GUInt64, essentially an unsigned long long) to 'size_t' (also essentially an unsigned long long). So, utilizing a cast is not problematic in this context. However, I noticed in the function description it states "used for small memory allocations," which prompts me to inquire if there is an alternative calloc function for larger memory allocations. If not, I will proceed with casting the variable in all instances. Nonetheless, I would appreciate knowing if there is a cleaner solution available. Thank you for your assistance. /************************************************************************/ /* CPLCalloc() */ /************************************************************************/ /** * Safe version of calloc(). * * This function is like the C library calloc(), but raises a CE_Fatal * error with CPLError() if it fails to allocate the desired memory. It * should be used for small memory allocations that are unlikely to fail * and for which the application is unwilling to test for out of memory * conditions. It uses VSICalloc() to get the memory, so any hooking of * VSICalloc() will apply to CPLCalloc() as well.
