outputting to file?

What am i missing? This creates a file but does not write to it.

Code:

void foo (struct* current, char inputID) {

FILE *stdoutReport;
    char *reportFile;

    if (current != NULL) {
        if (strcmp(current->categoryID, inputID) == 0) {
            strncat(inputID, ".report\0", REPORT_SIZE);
            reportFile = inputID;
            stdoutReport = fopen(reportFile, "wa");
            if (!stdoutReport)
                printf("Error creating file. %s", reportFile);

            fprintf(stdoutReport, "Category %s - %s - Detailed Report\n",
                   current->categoryID, current->categoryName);
            fprintf(stdoutReport, "----------------------------");
            fprintf(stdoutReport, "-----------------------------\n");

O_o

That "wa" there isn't a valid mode of operation.

You need to look at your fopen() options again... I don't believe you can combine w and a.

stdoutReport = fopen(reportFile, "w");

Yeh thanks all. Was late and i was tired. Didn't even have fclose() in the code.
