Um. Maybe you've been using perl too much lately.
Try the following.
#include <strings.h>
if (strcmp(castedPtr->tname, "") == 0)
/* check if string is empty and display warning message */
missingInputCB (w, clientData, callData);
else { /* delete file name that matches the value of castedPtr->tname */
char *command = (char*)malloc(strlen(castedPtr->tname)+6);
if (!command) {
crash_and_burn();
}
strcpy(command, "rm -f");
strcat(command, castedPtr->tname);
system(command);
free(command);
}
Something to that effect should work.
