int access (
/* SYNOPSIS */
const char *path,
int mode)
/* FUNCTION
Check access permissions of a file or pathname
INPUTS
path - the path of the file being checked
mode - the bitwise inclusive OR of the access permissions
to be checked:
W_OK - for write permission
R_OK - for readpermissions
X_OK - for execute permission
F_OK - Just to see whether the file exists
RESULT
If path cannot be found or if any of the desired access
modes would not be granted, then a -1 value is returned;
otherwise a 0 value is returned.
