the hasMemory of bytes
# Params
- bytes : The number of bytes you require. If the amount of available memory is greater than or equal to the bytes, the function returns true.
# Examples
hasMemory(2*1024*1024) -- returns true if 2M available
if hasMemory(500*1024) then open stack "Explore Multimedia"
# Description
Use the hasMemory function to check whether there's enough memory available for an action (such as displaying a large graphic) before you do it.
This function is only partially implemented, and may not return useful values on some platforms. It is included in LiveCode for compatibility with imported SuperCard projects.
>*Cross-platform note:* On Mac OS, the value > return depends on the amount of free memory in the > application heap and does not take available temporary memory into > account. This means that even if the hasMemory function > returns false, there may be enough system memory available > for the task, since LiveCode uses temporary memory when necessary.
