So I have a file stream from a parent process to a child - and most of the time it works fine. However, when reading from it multiple times quickly, using fgets() will return NULL and the error is set to "resource temporarily unavailable". The problem is intermittent - and running the script that does the reads will sometimes have fgets return NULL and sometimes wont.

Could anyone help me stop this error from happening? Thanks!

Is this safe to do? (does fgets terminate the buffer with null) or should I be setting the 20th byte to null after the call to fgets before i call clean. // strip new lines void clean(char *data) { while (*data) { if (*data == '\n' || *data == '\r') *data = '\0'; data++; … >>> More

With one of the tests I'm running on this code, there are a few hundred spaces after the data that I want - which causes the program to fail. Can someone advise me as to how to ignore all of these extra… >>> More

beginner question here, I haven't been able to find examples that relate. I'm working on a C program that will take integer input from stdin using fgets and sscanf, and then write it to an array. However, I'm not sure how to make fgets write to the array. #define MAXINT 512 char input[MAXINT] int… >>> More
