strncpy

這是一個 strncpy 的範例:

int safe_strncpy(char *dst, char *src, int len){ int count=0; if(len <1) return 1; // Null pointer is dangerous. if( dst==NULL || src == NULL ) return (-1); for(count=0; count<len; count++) { dst[count]=src[count]; if(src[count]=='\0') break; /* String end of str */ } return 0;}
