ftemp

warning

This function starts with lowercase letter.

Description

Creates a file in the "tmp", "temp" or root directory with random name for reading and writing. The file is deleted after fclose() is used on the file.

Examples

// Create a temporary file stream
new File:t_handle = ftemp(),
// Declare "handle"
File:handle,
// Declare "g_char"
g_char;
// Check, if temporary file stream is open
if (t_handle)
{
// Success
// Open "file.txt" in "read only" mode and check, if the file is open
if (handle = fopen("file.txt", io_read))
{
// Get all the characters from "file.txt"
while((g_char = fgetchar(handle, 0, false)) != EOF)
{
// Write character in lowercase into the temporary file stream
fputchar(t_handle, tolower(g_char), false);
}
// Close "file.txt"
fclose(handle);
// Set the file pointer of the temporary file stream to the first byte
fseek(t_handle, _, seek_begin);
// Open "file1.txt" in "write only" mode, and check, if the file is open
if (handle = fopen("file1.txt", io_write))
{
// Success
// Get all the characters from the temporary file stream
while((g_char = fgetchar(t_handle, 0, false)) != EOF)
{
// Write character into "file1.txt"
fputchar(handle, g_char, false);
}
// Close "file1.txt"
fclose(handle);
// Set the file pointer of the temporary file stream to the first byte
fseek(t_handle, _, seek_begin);
}
else
{
// Error
print("Failed to open file \"file1.txt\".");
}
// Open "file2.txt" in "write only" mode, and check, if the file is open
if (handle = fopen("file2.txt", io_write))
{
// Success
// Get all the characters from the temporary file stream
while((g_char = fgetchar(t_handle, 0, false)) != EOF)
{
// Write character into "file2.txt"
fputchar(handle, g_char, false);
}
// Close "file2.txt"
fclose(handle);
}
else
{
// Error
print("Failed to open file \"file2.txt\".");
}
}
else
{
// Error
print("Failed to open file \"file.txt\".");
}
// Close the temporary file stream
fclose(t_handle);
}
else
{
// Error
print("Failed to create a temporary file stream.");
}
