How to execute a bash script using "system ()" when there are spaces in the file path?

Question

I created a simple bash script called "myscript.h". I gave it the .h extension for reasons that I will not disclose here. This bash script lives in "/ var / ftp / something with spaces".

From the terminal, I can enter "/ var / ftp / something with spaces / myscript.h", and the script works fine.

However, from my C program, I print

system("/var/ftp/something with spaces/myscript.h")

and he complains that "/ var / ftp / something" was not found. I changed my system call to the following slashes:

system("/var/ftp/something\ with\ spaces/myscript.h")

However, he still complains that "/ var / ftp / something" was not found. Assuming I can't change the directory names, how can I get around this?

Thank!

Just enter the file name in single quotes
