◆ my_stpcpy()

static char * my_stpcpy ( char *  dst,

Copy a string from src to dst until (and including) terminating null byte.

Parameters
dstDestination
srcSource
Note

Parameters
dstDestination
srcSource
nMaximum number of characters to copy.
Note
src and dst cannot overlap Use my_stpnmov() if src and dst overlaps.
Returns
pointer to terminating null byte.
