xstrlen

unsigned int xstrlen( long src );

Description

Return the length of the string in xmem pointed to by src. If there is no null terminator within the first 65536 bytes of the string, then the return value will be meaningless.

Parameters

src

xmem (linear) address of the first character of the string. Note: to perform a normal null-terminated search, ensure that src is in the range 0..2^20-1. If the MSB of src is not zero (i.e., bits 24-31) then that character will be used to terminate the search rather than the standard null terminator. E.g., to determine the length of a string terminated by '@':

xstrlen(paddr(my_str) | (long)'@' << 24);

Return value

Length of string, not counting the terminator.
