strncat

Valid for: CANoe DE • CANoe:lite DE • CANoe4SW DE • CANoe4SW:lite DE

​
Function Syntax

void strncat(char dest[], char src[], long len);

​
Description

This function appends src to dest. len indicates the maximum length of the composite string. The function ensures that there is a terminating “\0”. Thus, a maximum of len - strlen(dest) - 1 characters are copied. Note: Unlike the strncat C-function, rather than the number of characters to be appended, len indicates the maximum length of the composite string, including the terminating “\0”.

​
Parameters

  • dest: Target string to which characters are appended.
  • src: Appended string.
  • len: Maximum length of composite string including terminating ‘\0’.

Example

char s[20];
strncpy(s, "Vector", 10); // s is "Vector"
strncat(s, " CANoe", 19); // s is "Vector CANoe"
strncpy(s, "Vector", 10); // s is "Vector"
strncat(s, " CANoe", 11); // s is "Vector CAN"
