NAME
       memparse - parse a string with mem suffixes into a number

SYNOPSIS
       unsigned long long memparse(const char * ptr, char ** retptr);

ARGUMENTS
       ptr
	   Where parse begins

       retptr
	   (output) Optional pointer to next char after parse completes

DESCRIPTION
       Parses a string into a number. The number stored at ptr is potentially suffixed with K (for kilobytes, or 1024 bytes), M (for megabytes, or
       1048576 bytes), or G (for gigabytes, or 1073741824). If the number is suffixed with K, M, or G, then the return value is the number
       multiplied by one kilobyte, one megabyte, or one gigabyte, respectively.
