# [NAME](#NAME)

streqvmap - Set the character mappings for the streqv functions

# [SYNOPSIS](#SYNOPSIS)

#include <*your-opts.h*>  
cc \[...] -o outfile infile.c -l**opts** \[...]

void **streqvmap**(char *from*, char *to*, int *ct*);

# [DESCRIPTION](#DESCRIPTION)

Set the character mapping. If the count (**ct**) is set to zero, then the map is cleared by setting all entries in the map to their index value. Otherwise, the "**From**" character is mapped to the "**To**" character. If **ct** is greater than 1, then **From** and **To** are incremented and the process repeated until **ct** entries have been set. For example,

```


    streqvmap('a', 'A', 26);
```

will alter the mapping so that all English lower case letters will map to upper case.

This function name is mapped to option\_streqvmap so as to not conflict with the POSIX name space.
