我在我的代码奇怪的地方有段错误。这是在最后的陈述。任何人有一个想法,为什么我得到段错误?段落错误与stderr
void processArgument(char argument[]){
FILE *sketcher;
FILE *fp;
fp = fopen (argument, "r");
sketcher = popen(Exec_c, "w");
if (fp == NULL){
printf ("Could not open pipe to %s\n", argument);
exit (EXIT_FAILURE);
}
if (sketcher == NULL){
printf ("Could not open pipe to %s\n", argument);
exit (EXIT_FAILURE);
}else{
parseFile(fp, sketcher);
if(fclose(fp)==EOF){
printf("couldn't close pipe to %s.\n", argument);
exit(EXIT_FAILURE);
}
if (pclose(sketcher) == -1){ //if (pclose(sketcher) == -1){
fprintf(stderr, "draw_line error: couldn't close pipe to %s.\n", Exec_c);//fprintf(stderr,"",E);
exit(EXIT_FAILURE);
}
}
}
