I have written a program that manipulates files and I sometimes to delete a file. So I searched and found the remove() function in the stdio header file in C. The problem is that sometimes works and sometimes not. Sometimes the file is deleted, other perror() shows a message that says permission denied but I have not specified any special permissions on the file. As a matter of fact the file has been created a little before by another function. Any special conditions that I have to consider? Here is the load function that creates the file: ... int loadF ( const char *filename, plist_t pl, int size, int createFlag ) { FILE *pFile = NULL; pnode_t pn = NULL; int fsize; int total; int i; // Get file stream. pFile = fopen ( filename, "rb" ); if ( !pFile ) { // File does not exist. if ( createFlag ) { if ( !createF ( filename ) ) { return 0; // fail } } else { // abort perror ( "loadF:fopen" ); return 0; } } // Confirm that we have opened the file stream. if ( !pFile ) { pFile = fopen ( filename, "rb" ); if ( !pFile ) { perror ( "loadF:fopen:" ); return 0; } } // Check if list has not been initialized. if ( pl == NULL ) { fclose ( pFile ); pFile = NULL; return 0; // abort } // Get the size of the file. fseek ( pFile, 0, SEEK_END ); fsize = ftell ( pFile ); rewind ( pFile ); // Check if the file is empty. if ( !fsize ) { fclose ( pFile ); pFile = NULL; return 1; // No data to load, continue. } // Get the total number of structures in the file. total = fsize / size; // Allocate memory for a node to transfer data. pn = (pnode_t) malloc ( sizeof (node_t) * sizeof (char) ); if ( !pn ) { fclose ( pFile ); pFile = NULL;
