Syntax
void strncpy_off(char dest[], long destOffset, char src[], long max);
Function
This function copiessrctodest.maxindicates the size ofdestin bytes. The function ensures that there is a terminating '\0'. Thus, a maximum of max-1-destOffset bytes are copied. Bytes are overwritten indeststarting atdestOffset.
Parameters
dest Destination buffer
destOffset
Offset in destination buffer
src
Source string
max
Is used to determine the maximum number of copied bytes.Must not be larger than the size ofdest. A maximum of max-1-destOffset bytes are copied.Ifsrcis shorter than that, bytes are only copied until a terminating '\0' is encountered.
Return Values
